People will do basically anything to fix junctions except install roundabouts.

I wonder how many millions of days humans sit in cars and look at empty crossroads and a red light.

I think one of the big issues they started with multi-lane roundabouts, at least near me. Single-lane roundabouts are significantly safer and easier to understand. This would have been the way to go. Instead they got a bad reputation from the start due to the complexity involved in the multi-lane ones.
