I wouldn't say I "like" buses -- they are large, cumbersome, and the segmented buses sometimes require creative tactics to avoid when they and up blocking intersections or generally getting in the way. But I don't think I've ever encountered an intentionally mean driver.

I do like racing the buses. My commute home is almost all uphill, and I consider it a victory when I start next to the bus that takes the same route and beat it. (On the downhill, of course, there's no contest.)

As for the horn tapping, I wish I could understand that. My grandfather used to do that to every cyclist he passed. (Fortunately, he doesn't drive much now.) I tried to explain that it's annoying to the cyclist, and that with some bad luck he could startle the cyclist resulting in unpredictable behavior (like falling in front of the car or whatever). He was convinced that it was the polite thing to do, to let the cyclist know that he was going to pass. I don't know if that was some protocol back in the thirties, but I never could talk him out of it.
