How does traffic flow slow down with no obvious reason?

518 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

Tailgating. Seriously, that’s all it is. People tailgate and don’t have the necessary stopping distance to not stomp on the brakes.

Also means that people can’t enter or exit the highway because there’s no way for the traffic to ‘absorb’ the small adjustments in speed.

Tailgaters are the absolute worst.
