You have that right? Show me where such a right is enumerated. Make no mistake, the mere presence of all of those cars on a public road is a privelege. Not a right. If a bird drops a load right onto your freshly detailed hood, are you within your rights to pull out your .40 and blow it away? Park your car under a tree or power lines, you shouldn't be shocked it's going to get crapped on. Park your car in a bad neighborhood with the doors unlocked, you shouldn't be shocked to find it missing. Park your car in NYC, you shouldn't be shocked that someone parks like this. This is not a justification, as I've said before there is clearly a lack of respect for personal property; I'm just saying, you shouldn't be shocked by this. I never said I wouldn't take offense to people touching my car. The mistake you're making is projecting your/our "car enthusiast" unwritten code of ethics onto people who may not be car enthusiasts at all. So yes, you can believe it. If you're in a city where it's normal for people to be using each other's T-shirt as a napkin, then so be it. Unfortunately, I know of no city where this is normal. Also unfortunately for your example, I can think of a city where parking like this might just be considered normal. BTW, care to guess what city this is in?
