There are for sure studies on this. I remember seeing one from Seattle specifically, but others as well.

Speeding up and slowing down causes an accordian effect that results in slower speeds for everyone. The time it takes to reduce speed or stop, then recover to a higher speed is higher than just cruising at a middle speed.

I drive a manual and I never hurry in my commute, at rush hour or when there’s some accident on the highway people get crazy, they look like ants on a kicked nest, i just try to drive at a constant speed, and most of the time it takes me almost the same time, compared with a reference vehicle, to get out of that craziness without any stress.
