Your part of the problem. https://phys.org/news/2007-12-traffic-mystery-mathematicians.html https://phys.org/news/2007-12-traffic-mystery-mathematicians... Mathematics has shown that each time a brake light flashes it forms a wave that miles behind causes total stoppage because for 2 minutes people hit their brakes lightly slowing down with each person behind slowing a little bit more.

I touch the brakes only when I'm slowing down, but not necessarily to cause me to slow down. And I only do that when people are following too closely behind me. I've been rear-ended by people following too closely who failed to recognize that I was slowing in time to slow themselves down. I'd rather be pragmatic and warn them off before an accident occurs. By "will be slowing" I mean: I have removed my foot from the throttle or stopped cruise control but my vehicle has not started to appreciable slow yet.
