Every day I go to work, there is a left-side ramp that I take that goes from one interstate to another.
Normally, the ramp is two lanes and you can drive 50 mph, but with the construction it is now down to one lane and 30 mph.
So what you have is people in the left lane backing up and sometimes going stop-and-go, while traffic in the straight lane to the right of you going 65 mph.
When I'm in the left lane and see the slow/stopped traffic ahead of me, I slow down gradually or coast up to the traffic backup.
What then happens is the traffic behind me will see me doing this, and then they will swerve to the right into the next lane, then swerve back in front of me, then drive 65 mph up to the backed-up traffic where they will then jam on their brakes to slow down and stop.
And every day, there are 3-4 accidents here because people always misjudge how long it takes for them to stop their car.
