One of my pet peeves with drivers these days is no one is able to get up to speed to enter the highway on an entrance ramp. They just wander out into traffic at whatever speed they happen to attain. I have seen as low as 48 mph entering a 70 mph freeway. Or, get to the end of the entrance ramp and THEN look for a gap to enter traffic. So often there are significant skid marks from heavy trucks around entrance ramps because of these idiots. But lately, other idiots. Yesterday I saw a driver cross from the center lane in front of a semi, over the barrier line area of an exit ramp. If a bike had been on the other side of the truck it could have been dangerous for the cycle. Two weeks ago, approaching an exit ramp with two exit lanes, one to only exit, the other to exit or go straight ahead. Idiot car driver in the far right lane suddenly cuts across both exit lanes and the barrier area to get into northbound traffic. When in my car, especially on my bike, I stay in the far left lanes if I don't need the exit. If I need the exit I try to avoid having any vehicles around me as I exit. Distracted idiot car drivers, geez.
