How does traffic flow slow down with no obvious reason?

532 views

Ok let me try and make this make sense; when driving on the motorway/highway, why does traffic come to a slow or stop at some points and then speed up (with no obstructions/traffic lights etc) and flow freely with no change in the road or conditions?

If it’s clear up ahead, why do cars slow down or stop when nothing is blocking them in the distance? It’s like it slows down for no reason then just regains speed and traffic flows fine. Drives me insane

primarily caused by following too closely. the driver of the first car sees a cop ahead, or a shredded tire in the road, or, if in florida, for no reason at all, taps the brakes…..driver behind them following too closely has to do the same….and this just cascades back.
