A DC area posting on what many drivers do that make other drivers crazy. Many of these things apply to drivers in every city and a couple I see all the time in St. Louis.
8-not accelerating up to high way speed when you're on an onramp to the interstate. St Louis drivers seem absolutely incapable of doing this for some reason. A couple of area examples: On 64 westbound at Kingshighway and at Hampton, 170 northbound from anywhere to the airport. Cars entering those highways, and there are a lot of them all the time, too often hesitate and slow before trying to merge into traffic. This makes the cars behind them back up and the cars on the highway try to move over one lane.
It's particularly troublesome at the Hampton onramp merge because the right highway lane soon becomes an exit only to Clayton Road which means botch all as the mergers have to not only get onto the highway in a timely manner but also get over to the second lane. If they do this too slowly, which most do, it causes not a few nervous moments for other drivers.
3-Lazily moving into turning lanes. I see this a lot at Belt Line and 159 northbound in Collinsville. The left turn lane is quite lengthy but a lot of drivers give no indication they will move into it until they're almost at the stoplight. If you're like me and behind one of these people and you've moved into the left turn lane as soon as it appears, there's apt to be a close call when the former driver moves at the last minute.
This is a fun read, as are the comments.
