I don't think anyone here is saying they will take their business elsewhere. Theres no action being proposed by me except to say that the policy outlined in the beginning of this thread is fucking STUPID and I think anyone who finds it to be reasonable is equally stupid, at least where this is concerned.
Does that include you? I don't know. You still have not weighed in on that.
I think it makes sense to try to nab people who are living here without registering, and one of the only ways to do that is to watch for cars that park here all the time. Since GGW is the only person I have ever heard of so far who has experienced this, and he admitted that he parks here a lot, it seems reasonable. If they were nabbing everybody who parked more than once in a 180 day period, that would be ridiculous.
Beyond that, I am highly skeptical of the description of any regulation described on this board, especially with people like Jaguar around believing in lizard people and equating parking enforcement to Nazism. So that's a second reason why I'm not too worried about this.
As for DC versus suburbs... as usual it is a false dichotomy. in many suburban neighborhoods near bar areas, like Clarendon, you can't park on side streets at all if you don't live there. All neighborhoods near bar/restaurant areas struggle with this same issue, regardless of locality, and the tendency is to favor the people who actually pay taxes there.
Finally, these type of restrictions are usually brought on by neighborhoods, not by lizard people or officials with aspirations of Nazism. And it comes about because people get sick of coming home and finding no spaces on the street they're paying taxes for.
