Hi Pro Hwang,
Interesting animation of reaction time, car braking to a stop..... .
I would suggest that you consider adding a constant of 0.5 second for mechanical reaction time for the brakes to the perception/reaction time of human.
The total reaction time taken would then be more realsitic - real world situation, before the brakes starts to engage.

Dear Prof. Fu-Kwun Hwang,
I am a high school student in the 12th grade and San Marino High. In my physics class this week we were assigned to find an equation that governs the use of any part of an automotive vehicle. Searching for an equation, I came upon your site, more specifically, your simulation of reaction time and car accidents. I know time is very valuable, and you must be very busy, but if you could send me an equation that governs the the breaking distance with respects to reaction time, velocity, friction, etc., I would greatly appretiate it. If there is no such equation, if you could send me any mathamatical proof for how something relating to mechanics works, that would be appretiated as well. Thank you for your website, which is very informative and helpfull.
