I hate drivers who refuse to let me in, even though they can clearly see that my lane is disappearing. What do they expect me to do, vanish in a puff of smoke? Or do they actually want me to go off the side of the road and crash into a ditch?
Especially when, after I manage to get into the lane despite their best efforts, they refuse to back off and give themselves adequate stopping distance. As if no one ever has to slam on their brakes.
Especially when, just ahead, traffic is dropping from 50 mph to a dead stop. So I have to slam on the brakes, but can’t. If I brake too hard, the idiot behind me will crash into me. If I don’t brake hard enough, I’ll hit the car in front.
Today, I found the narrow window between braking too much and braking too little. But there are few driving situations that make me more nervous.
