I always wondered if you need less than two seconds if you're behind a vehicle that can't stop very fast (e.g., a large truck). Your superior stopping rate could make up for the decreased reaction time.
- jongraehl 17y agoThis can fail horribly. Consider that the truck can decelerate faster than its solo braking ability by hitting a wall or another car. Chain reaction pile-ups aren't only about reaction time. So, you can count on not being forced to collide by the driver acting alone, but it takes some extra margin to reduce the threat of rear-ending by a poor braker following you, and to account for obstacle-assisted braking by the driver in front.
