Figures, when I go away on vacation Lifehacker does a commute-related post. Only in this case, most of their tips (which actually come from the UK) don't make much sense.
* Don't misread the horn? If it's a quick toot or two, then I know it's to get my attention for something. If he's been leaning on it for the past 30 seconds, I get the message. What's to misread?
* Make eye contact? There are places in the US where that will cause more road rage than it prevents.
* Limit your commute to 15 minutes? Bite me. Very few people I know have the luxury of choosing the length of their commute.
* You don't own that parking space. You're right, but just because somebody's leeching it when there's a perfectly good empty one 2 spaces down does not mean I feel the need to hurry myself along.
* Late merging (when some putz waits until the last second to squeeze in to your lane because his is coming to an end) is ok. You know what? Don't care, still hate you. That's one of those cases where statistically it might work (because the cars are spread across more lanes for a larger physical space), but psychologically it's a nightmare.
