It takes micro-seconds to turn your head enough to see what's around you. If you run into someone in front of you because you glanced around you were FOLLOWING WAY TO CLOSE.
And the reason there are rear end accidents.
Merging into tightly spaced interstate traffic, following another car in front takes a lot for granted the person front will not panic at last moment and hit their brakes at the end of the merge lane without any warning.
.
(60 mph = 66/ft/second, or about the time one takes to a "quick"(?) glance over one's shoulder and judge speed, distance, dynamic positions, and intentions of other cars maybe even looking over their shoulder?
)
QED
Stumpy is right, if you rear end someone simply because of a milliseconds of having your eyes off the road you're following to close. Simply looking down at the dash would cause an accident if that was the case.
As far as your reply, even if someone panic stops in front of you, if you hit them you were too close. Their car didn't stop instantly, it take time and distance to stop a vehicle. The higher the speed driven, the longer the distance required to stop.
The problem is that people drive with one car length between cars at 70 mph and think that they have time to react.
They don't........
