My only problem with the school busses around here is that they're too timid. I had one that was going to turn right into the high school this morning; he hung behind me for about 1/4 mile. This was on a road with hardly any traffic and a dead turn lane in the middle (shared left-turn lane that is rarely used, and easy for people to use as a passing lane).

About 10 minutes earlier I had one hang behind me for about 300 feet because he had a stop to make just ahead.
