In reality, if they don't hit me I am OK. I would prefer that drivers simply obey the law and give me at least 2 feet. However, I have been road cycling for so long that I've gotten used to people passing me closely. It is pretty aggravating when people pass with a foot or less to spare, particularly when they usually have a lot of room in their lane that they aren't using. For some reason, school bus drivers seem to be some of the worst offenders.
