But, yeah, it's crazy how much crap you can find on a car's surface out there when you don't wash it often. OTOH, it rains so infrequently there that there's a repeated rinse cycle cars go through here that is missed that also helps allow some build up, too. Of course, there's no acid rain there. Then again... and so on.

The environments are different and each have their own harshnesses.
