This thread has got me thinking (always dangerous!) Checking the Highway Code on vehicle stopping distances, quite apart from the fact that many claim it is out of date over braking distances for modern cars, I was intrigued at its calculation of thinking, or reaction time. It claims that reaction time at 70 mph means that the vehicle will travel 76 feet before you react and start to brake. 70 mph is 103 feet per second, so to travel 76 feet represents a reaction tome of 0.74 of a second, which is pretty slow - I'm not complaining - better to be safe than sorry, and if they based their figures on folk who react more quickly than that it could engender a sense of false security in those who can't.
Have any of you ever had your reaction times tested?
