Methinks you haven't driven that much. I've driven well in excess
1,000,000 miles, and I can tell you that the sudden appearance of
objects in your drive path can happen whether or not you are paying
attention.


of course they can. what you miss is that if a driver can't avoid such
events, they were not paying attention and/or driving too fast for
conditions, and i'll add to that, and/or driving while intoxicated.


According to accident reconstruction studies, the average braking
reaction time (i.e. "event" - "apply brakes") is about 2.2 seconds.


human reaction time is generally about 0.3 seconds.

those with slower reaction times tend to crash.

A car-length is approximately 15 feet (177 inches).

Standard roadway in the busoness districts around here is 25 MPH (36
feet per second). Assuming an average driver, that means any "sudden"
change in conditions within 6 car lengths will result in either slamming
on the brakes, or an accident.


i was taught to follow at least 3 seconds behind.

of course, that never happens in the real world, which is one reason
why there are so many crashes.
