I wasn't aiming to call you out, as such. I just wanted to air my opinion, but thank you none the less for providing some sources :-) The 45 feet from 30mph is a common figure (the UK government's Highway Code uses it as well). The cars I tested are normal cars, but I concede I had good tyres and I always choose smooth roads to test on. Once you include: 1. Driver ability 2. Vehicle quality 3. Road quality 4. Prevailing conditions 5. 4 passengers plus luggage I guess you can explain the difference.
