Matt the reason why the delorian flipped was because it is a back wheel power vehicle and when you increased the horsepower the front and the back of the car got desyncronised
If you want to revisit this, go for a similar idea to the last 'limo driving on top of wheels', but pick the vehicle with the biggest wheels, high horsepower, and make the prop/bridge driving wheels as small as possible - basically trying to gear up the speed. I can't imagine it going well, but the small wheels will rotate a lot faster than the geared down version here.
This actually doesn't make a difference because it will only increase the angular velocity, not the actual velocity of the wheel where it touches the ground.
U got it backwards. You want a vehicle with small wheels driving a big wheel. If you can give the big wheel the same angular velocity as the small wheel, the lineal velocity will be much greater than the small vehicle would have on its own
Just as an addendum to the three people saying about angular/linear speed: I think I'd agree in the real world. I'm more wondering about the slightly glitchy nature of Poly Bridge 3's simulation. My guess would be that changing the gearing will either make it go faster (by potentially reducing the amount of lift off from higher horsepower) or glitch it's way into the stratosphere (because, well, you saw the video). Either way should be entertaining.
Fun fact : the delorian is not a sports car, it's made out of stainless steel making it quite heavy. The infamous 88MPH for a delorian to time travel is impossible, the delorian can't reach 88MPH.
DeLoreans can go over 100mph... 100% of vehicles of its era sold in the USA could only show 85mph on the speedometer due to federal law, but that had nothing to do with the performance
Hi, Mechanical Engineer here. Similar to how a torque-to-speed gear box works, perhaps you should try making a gear-esk shape (with teeth and such), where the vehicle turns a larger gear, which then meshes with and transfers rotation to a much smaller gear. If done right (and due to the game appearing to not account for torque losses with speed increases), it could be possible to get the vehicle going crazy speeds, even with a super slow vehicle.
Hi Matt, just a comment to thank you for your content and particularly on Polly Bridge. I'm a French student, and you have inspired me to work on bridges and to present these masterpieces of engineering 🤌 in my final oral exam. Hope I will convert my examiners to the bridge religion.
Just a thought, flip an entire line of limos upside-down, then put a road on it like a conveyor belt. Then put another limo on top of the conveyor. Should double the speed right? :P
Why not make a small wheel, put something a bit slower to prevent lag and bugs, and then create a bigger wheel around it and connect it to the smaller wheel? Physics will do the rest of the work. (bicycles and cars use a similar mechanism to control speed) edit: looking at the video I don't think the game simulates the effect of weight on speed so it might work with minimum speed too another edit after seeing what he did at the end: it would work better with the grip from your last version if you make it bigger and work the same way I described (it will also be more interesting considering that instead of making a car go faster inside another car you will make an actual engine that boosts slow cars with the power of ENGINEering). and another edit after reading some of the comments: I watch your videos mainly for the engineering part, I like seeing how things we would usually learn in school can be applied in everyday life, aka, gaming. That's why my favorite videos are the road simulators (specifically the parts where you recreated some real roads) and the simulators you play. I noticed that most of your community, in the comments at least, don't pay attention to this or just don't talk about it much, but I would love to see more thinking going into these videos, I'm in 10th grade, and if I can make up the idea above I can't imagine what a real engineer would do if he will actually try to make something unique. That's why I'm subscribed after all.
actually problem with wheelies is soved by adding more weight as center of mass is usually placed before rear wheel so it will pull rest of vechicle down
Boosh nailed it! It looked great in slow motion, but when you showed it in normal speed, you could realy see how fast it was going. Obviously the xS in the corner, stands for normal speed. And you were going so fast, that from the perspective of the observer it almost looked like the top of the S had flattened. (So it looked a little like this x5)
I will always love you're shenanigans but, I'm surprised that you didn't do a train like you did in poly bridge 2. Also Drae beat you on the leader board in MM-06 Cliff Brace lol just thought I'd let you know😂😁. Keep up the shenanigans, they always make my day.
I was literally wondering why you didn’t have a “truss me I’m an engineer” shirt yesterday. Only to find out I’m somewhat precognitive today. Now I can finally wear the ultimate engineering pun. Hooray!
Seemed like the spring tires were actually doing great, you just needed to provide lateral structure to them so they wouldnt slip. You tried providing the horizontal structure with steel beams but that doesnt keep the wheel from stretching or shrinking horizontally, that just helps support the weight of the vehicle, which was not an issue to begin with so you did not really fix the problem.
you were on the right track around halfway thru, the tractor or truck against the stiffer spoke big wheel... all it needed was a wheelie bar attached sticking out to a small wheel to stop it doing wheelies (like a drag racing motorcycle) 🏍 👍 you were right there!
Matt the issue you were running into with spring wheels is the same as when drag racer run into issues with the tires folding on them selfs and bunching up and they run into that issue when the air pressure is too low so the solution to your issues would be to increase the pressure of the springs.
Hello! Spinning a smaller inner wheel to the tractors' top speed and then making a larger outer wheel, like the tire you make but bigger, would make the outer wheel spin much faster. Plus, The springs help a lot, so maybe making a thin tire out of springs with a rigid structure will help give traction and rigidity. Look at a bicycle wheel.
Yes. To get the wheel tensioned like a bicycle wheel, you also need to have the springs pull instead of push. The large/small wheel setup is what almost all of this was missing. Nearly every setup was doomed from the beginning because the in/out speed ratio was 1, meaning it could never exceed the speed of the car.
I can pixture matt driving down the road, paddy at his side, calling bad drivers 'architects' and every so often saying ," oh look paddy were coming up on a bridge. You know ehat that means. A BRIDGE REVIEW!"
Well, at least Matt didn't try to sing in this one. Idea for change in game physics for PB4: each vehicle should be explicitly FWD, RWD, or AWD. That limo, on its own, could have been massively overpowered if it were FWD.
Hi RCe. you could take a monster truck and scale it up to 200%. The tires of the truck should therefore be larger than your chassis. When the monster truck is moving, the wheels on your undercarriage will spin slightly faster than the truck's wheels. Is similar to the gearbox, the smaller the last gear, the faster the vehicle.
7 Pg is actually 7,000,000,000,000 kilograms, or 7 billion metric tons. To put that in perspective, an Airbus A380 superjumbo jet has a mass of about 285 metric tons. That would mean that the limo has a mass equivalent to nearly 25 million A380s, the largest and heaviest passenger jet ever built. Heck of a heavy car.
You need to get a wheel as big as possible on the outside and as small as possible in the inside and then put a car in it. This way the car does travels a short distance to turn the wheel one time around and the outside of the wheel travels the a lot more distance in the same time. This means the outer side travels faster than the car and this way you can travel faster than the car itself. It's kind of a makeshift gear. Have not tried it, partially because i do not own Poly Bridge 3, but from the physics side of view it should theoretically work.
So the plan to make the limo go faster was to have the limo’s small wheels drive some bigger wheels effectively working like a small gear driving a larger gear. Not sure why that didn’t work, I think the game is broken 😂
7:26 This looks like the airless tyre that companies have been telling us is "just around the corner" for years now. I think an engineer over on the Overdrive YT channel made a cheap version of that.
I timed your final creation (took some effort dues to the changing speeds, and was somewhat inaccurate due to the cuts) and got a time to completion of 24.25 seconds. assuming that the length of the track is the maximum possible (to make the speed as high as reasonable) the final speed works out to be at most 25.73 miles per hour, not the 50,000 as advertised.
I don't think Matt has seen slow-mo videos of drag cars starting. The drive wheels are twisted so hard they almost collapse, giving them a lot more surface area on the track and, as a result, a lot more traction.
Check out my BRAND NEW merch designs at: realcivilengineer.com
They qreat incredible btw love them!!!
I love u RCE
We all love our merch and your videos
You have to try this puzzle game! Hue. (I'm not sponsored it is just a good puzzle game).
You are epic
Matt: We need a wide wheelbase.
Also Matt for the rest of the video: Builds vehicles with the smallest wheelbase possible.
oh yeah :))
He should’ve used the flatbed truck
It's amazing you did this entire video without realizing adjusting the weight would stop the wheelies
I bet engineers have issues over engineering in real life as well.
i wanted to coment exactly that
thats engineers for you, we love overcomplicating things lol i do it all the time
Wheelies are fun tho

Angular speed won't be the same. Linear speed will stay the same so you can't increase the linear speed of the vehicle with this disign.
Just as an addendum to the three people saying about angular/linear speed: I think I'd agree in the real world. I'm more wondering about the slightly glitchy nature of Poly Bridge 3's simulation.
My guess would be that changing the gearing will either make it go faster (by potentially reducing the amount of lift off from higher horsepower) or glitch it's way into the stratosphere (because, well, you saw the video). Either way should be entertaining.
Best way to do it is with the vehicle inside of a wheel and then have massive tires. Acceleration won't be as good, but the top speed will increase
Fun fact : the delorian is not a sports car, it's made out of stainless steel making it quite heavy. The infamous 88MPH for a delorian to time travel is impossible, the delorian can't reach 88MPH.

12:35 it just blast itself off the map like in a Smash Bros game complete with the stress meter resetting!
really cool video, loved it!! also 13:13 poly bridge 2 does actually have this feature and is called 'edge bisect' + can be toggled haha
Worth specifically noting that it can be toggled in PB3 as well :p
16:40 the back wheel is behaving exactly like the tires on dragsters, so probably not necessarily a bad thing.

I didn't think It was possible to set land speed records on Poly Bridge, but I guess Matt can do them anywhere

17:29 put limos inside the custom circle and triple them to get the fastest vehicle

love the poly bridge videos matt keep doing them!!
you were on the right track around halfway thru, the tractor or truck against the stiffer spoke big wheel... all it needed was a wheelie bar attached sticking out to a small wheel to stop it doing wheelies (like a drag racing motorcycle) 🏍 👍 you were right there!
You should try attatching the wheels to shocks, not steel. That way it absorbs the bumps and wont bounce as much bounce. Great video!
you could have aded more weight to the delorian
Matt the issue you were running into with spring wheels is the same as when drag racer run into issues with the tires folding on them selfs and bunching up and they run into that issue when the air pressure is too low so the solution to your issues would be to increase the pressure of the springs.
I love your Poly Bridge videos so much (and all the other ones too) that I actually bought PB3 at release and I totally love playing it!
I love how confidently Matt talks about the “new” features in PB3 despite being completely wrong
Whatever bug occurred to fling the vehicle into space, use that same bug but learn how to steer it.
Matt you should try Scrap Mechanic! Maybe even Trailmakers, Automation, or Beamng! 😀
12:20 a bit of movement
you know you’re a good engineer when you worry about *aerodynamics* in a bridge building game.

12:39 this works because its like gears, try putting a tiny "engine" and a giant wheel
The wheels compressing is actually what happens with dragsters. Check a video of drag wheels in slowmo, it's really cool.

you can turn off that bisect thing in the options or set a hotkey to turn it on and off (i suggest B, it's unused)

2:35 I can imagine the guy in the car at the front just scream for help as he goes flying
Tire size only effects distance covered per revolution.
It's easy to spin small tires but the distance covered is a lot less.
Drag racing tires are left with less air than their max so they sort of fold and grip the road better and it's freaking ace to see in slow motion
I timed your final creation (took some effort dues to the changing speeds, and was somewhat inaccurate due to the cuts) and got a time to completion of 24.25 seconds.
assuming that the length of the track is the maximum possible (to make the speed as high as reasonable) the final speed works out to be at most 25.73 miles per hour, not the 50,000 as advertised.

Reid Captain builds a working bike, impressive…
Matt tries to build a car…whooosh
I will say having 3+ wheels would likely be required, so that power can be in the center of mass and prevent wheelies
No Man's Sky has bridges... y'all should look into that, Matt and team.
