If the reaction time is the same for wet as dry surface, such as not much spray, then why keep back 4 seconds in the wet instead of 2? Sounds like calculated from when wipers might have not been as effective decades ago. Assuming both cars have similar wet braking distance like the C-HR and the Golf. Secondly I wonder if instructors generally should teach overtaking more as too many qualified drivers falsely think that a close following distance is necessary for good overtaking. Thirdly I guess Golf driver was concerned the learner was going to turn left down that empty road Golf went, which might cost Golf minutes at the next traffic light (or roundabout where C-HR has less acceleration time - 7s vs 11s - and experience). If Golf is meeting slower drivers all the way through commute that few minutes might potentially add a third to their commute time. Just trying to understand Golf perspective - I still think their tailgating is very unsafe, and possibly reflects a terrible attitude!
Thank you for your comment Dee. Regarding distances, it’s simply due to reduced friction between the tyre and road surface. It’s also not uncommon for a car to take longer than double the distance it would in the wet depending on the tread depth, temperature, and amount of moisture on the ground. Your overtaking comment I think is a valid one and I’ll put a video up on it soon so thanks for the idea. I do teach it but I appreciate that it might be difficult for some instructors if they teach in city centre’s. Although most students are willing to do 2 hour lessons, some clients can’t and therefore, makes teaching subjects like overtaking and motorways impossible. And then we move on to the Golf driver. He may have been thinking that but I am sure his attitude towards a red L was the issue. When I reviewed the clip after, he didn’t tailgate the vehicles behind, nor the one he moved behind before turning. I conducted an experiment with an academic at Kings a few years ago to show the physiological changes that people have when seeing an L plate. I’ll put a video up on it when we complete our findings.
@@learntodrivetheeasyway I agree. I find it interesting that the 2 second rule seems to be a compromise between safety and some other factor like getting as many cars through an intersection as possible. Because at 60mph, if car ahead crashes and halts almost instantly, even with a (probably mentally impossible) instant reaction time, stopping in the dry will require about 3 seconds. As a typical driver can take almost 2 seconds to react and not brake fully the total stopping time can increase to 6 seconds. So I wonder if instructors and Highway Code should focus more on teaching stopping TIME (stopping distance seems like a distant abstract "theoretical" memory to many qualified drivers, and seems more difficult to calculate accurately in real world by comparison)

hello - am i able to have lessons / a mock rest with you before my test?
Hiya, send me a message on 07985586975 and I’ll see what I can do. Hopefully I can fit you in. 👍
