There are enough and people won't signal and move over to turn level, it will be used as an express lane and an acceleration lane.hopefully not as bad as there aren't too many entrances directly across from each other so you shouldn't have too much competition for turning left at the same spot.
The hey, I can get across two lanes, I'll just wait in the middle or travel down the middle until I can "barge" over.
I'd say 50% of more do not merge, they just cut in, daring the vehicle they are cutting off to hit them.
During the day the speed limit on RT % is 95 mph. It's not until after 10pm or so when the cops come out to play does the traffic slow down.
