There's a lot of really idiotic left turns across multiple lanes of traffic which are allowed outside of traffic light controlled intersections. Those lead directly to the "wave of death" situation where people (if they've been explicitly given such a wave or not) tend to try to bolt across traffic that they can't see coming. A traffic safety solution would be to just eliminate those left turns and run the lane divider bumps down the middle of those roads. Businesses would probably scream quite a bit since left turns into their parking lots would no longer be possible, but you'd cut out a ton of accidents. Suicide lanes turning across multiple lane would also similarly need to be removed. There are a ton of drivers who try to push through deeply stupid left turns in the middle of heavy traffic, because they're technically legal. Even making them do a U-turn at the next light would be safer (or yes, roundabouts, please).
