Is there a way/mod to prevent left turns through median on wide roads? And also U-turns on the middle of the road? And maybe prevent U-turns on all intersections by default?

Every time I have terrible gridlocks it turns out someone tries to turn left, and other wants to do u-turn, at same exact place in the middle of the road... Being seasoned driver myself, I can not stand the whole city doing nothing but U-turns on every damn occasion.

Sorry friends, I had to vent. Would appreciate any tip.
