What is it about driving a car that turns people who are probably otherwise normal adults into literal babies. Who screams (honks) as loud as they can, without a care for who it might bother? Babies. Who throws things at people when they are upset? Babies.
I think the requirements to be licenced to drive should include a basic understanding of traffic dynamics. When a person gets in your way so you can't speed through the lights and you end up waiting at a red, they didn't lengthen your trip at all and are not worthy of any directed rage. You were just going to be stopped by the next light and get to your destination at around the same time. If there is roadwork or an accident, everyone is in the same boat and no single person can speed you up or slow you down.
We've all collectively just accepted to be subjected to an enormous amount of noise pollution and sometimes deadly violence on the road simply because people can't understand and/or accept the realities of how driving infrastructure works. It's kind of mind-blowing if you consider it.
