Between perception and reaction time, you’re already at approximately 1.5 seconds. At 65 mph, that’s roughly 140 feet.
(Source - my Dad investigated hundreds of accidents. He taught me how to drive and we covered this math in detail.)
- Natsu 4y agoIt wouldn't work for everything, but you can cut that time by preemptively reacting to conditions. Say you're going around a blind corner, you can start slowing just because your visibility is lower and you don't know what's over there. Or you can see cars who intend to move over several lanes at once and kamikaze into the lane ahead of you and slow down because you know that all the people in front of you are likely to brake due to this. There are quite a few scenarios where I spot trouble before it happens and have an effectively negative reaction time with respect to whatever is causing people ahead of me to brake.
