more could all be alleviated if we adopted the American approach of turning left being allowed at a red light if it’s clear.
It can more often be dangerous in many cases which is why you’ll often see the sign no right turn on red there.Turning left ( or right there ) generally creates the same conflict as traffic crossing through the junction does/would
The best compromise is the no lights or roundabout and all entries stop.Its a lot easier and safer for all traffic in all directions to then merge avoiding each other from stationary.
