[@laneevans2498]

Very interesting. Pretty soon there will be no data we can't access. Thank you. le

[@scottnaramore7705]

Useful info. He does love the word "dynamite."

[@daniellawson5127]

I've seen a few manual non gr corollas come in after moneyshifts, luckily for them the rockers just pop out and are found laying beside their corresponding valve/spring. Did you guys pull EDR/VCH event data? Curious to know what rpm everything came apart at?

[@silvermoonbaby5622]

I'm a materials engineer so I have some basic understanding of the science involved in vehicular collisions. I just watched Day 25 of the Karen Read trial and the "Collision Expert" from the Massachusetts State Police Trooper Joseph Paul testified about his "reconstruction" using EDR data tech stream and I was left in confusion on how he was interpreting the data. When asked about what the triggers, key cycles, braking force, momentum, final rest, etc are, I could not understand his explanations. It sounded like word salad to me. This video made me understand why what I heard in the "expert" testimony did not make any sense.

[@kaptnawesome]

Trial brought me here too. There is so much wrong with that testimony. I'm looking forward to cross on Monday

[@cassiec2519]

Don’t know if you are going to see this but Karen Read brought me here too. I found the “trigger”. Trooper is wrong, it means that in reverse the vehicle was going too slow in comparison to where the gas pedal is being pushed ie: stuck in the snow

[@kaptnawesome]

@@cassiec2519 I agree

[@silvermoonbaby5622]

I was questioning my knowledge in physics while watching the testimony. Alan Jackson's cross examination of Trooper Joe Paul is going to be brutal. I am so excited to hear from the defense's experts who have solid credentials.

Hi how do I open PDF for wiring system with Techstream?

[@jshepard152]

3:26 So much for the common claim that the car saves data for only 3-4 weeks. Six years isn't really compatible with that. How does one go about deleting this old driving data?

[@Boozer20]

You people are cool with this? Where is the option for someone to opt out of this? What if someone doesn't want to participate in this invasion of privacy. This is crazy, and even crazier that people just accept things like it's not a big deal. Good thing our government is always on the side of it's citizens and would never do anything to harm them. If that wasn't the case, this would be scary.

The option is to not purchase any vehicle from the last 20 years 😂
