One of the more interesting discussions I have had on this issue was with a Driver's training instructor who was a retired police officer, RVer and an accident investigator, His training in these matters went way beyond mine or the average cop on the road's.
I ask him: When you are using skid marks to estimate the speed of a vehicle.. Does it make a difference if it's a car or a semi truck (NOTE on a semi all wheels brake) and his answer was "NO"
Yet in the law, it makes a difference.
CLEARLY if the formulas used by the police, I might add around the WORLD, say the skid marks are the same for all vehicles with all-wheel braking, no matter what the size...
And the government feels the need to give me more room to stop my House than my Car.... I got to have brakes on the towed to make it stop faster.
Once braking starts the rate of deceleration is about the same. But the large vehicle with air brakes requires the extra distance because of the lag in the air brake system.
