, you appear to have missed that the truck slowed down, then went right, and the explorer was going forwards in the opposite lane.
I saw all of that. Are you being obtuse?
Apparently, around here, proper following distance is like working out. No one wants to do it, but deep down they know they should.
If the LEO was back further, he likely could have swerved right because there would have been the reaction time to do so. It's not a difficult concept.
