bumper hung 

Being stuck behind a slow moving car with nobody in front of them and unable to make a safe lane change. The traffic in the other lane is moving too quickly to make the lane change.

I'd try to get in the fast lane, but I'm bumper hung.

The left lane is going at 65mph, but I'm in the right lane going 30 behind a Buick with grandpa behind the wheel.
