Iirc, the answer is to have someone drive slowly and let other cars pass. It creates a buffer zone that regulates the flow back to normal pace. Or at least that’s what I remember from New Scientist’s video from like a decade ago.

Only ever have to ask, my friend
- Lemminary@lemmy.world 2 months ago- untorquer@lemmy.world 2 months ago- I used to just idle when traffic moved. Slowed down way before i was even close to the car ahead. Played a game where i was trying to move at a constant speed or max fuel econ. Much less stressful to always be moving than gas/brake every 10s, even if you’re moving 5mph. - Really helps to look 3-4 cars ahead for brake lights. 
- HeyThisIsntTheYMCA@lemmy.world 2 months ago- not slowly, just leave room 
 
- Jax@sh.itjust.works 2 months ago- Nope that’s just a negative picture of a guy

It happens when people tailgate. They over react and it causes an according effect.

Or when people drive too aggressively and cut someone off, causing them to slam on their brake.
