So, you think you should do anything you want just because you can? Thank god I don't live next door to you as you sound deeply inconsiderate. Personally, I try to think of others rather than thinking "fuck 'em".
No Soupdragon, I'm talking about this particular instance. So I can get my head around the idea that people might park considerately in a free parking area - but I don't think that goes so far as to be a requirement, because free parking means it is for everyone's use, so they should not be pressured not to.
And of course I generally think being considerate to others is important and do that in my life all the time. But like Bassoon said, this particular issue is about convenience for everyone, not just about people on a particular street. What about consideration for people want to park in a free parking area? That's immoral, but it's not immoral to have a "get orf my land" attitude about what is not even your land?

Nice. I'm actually very considerate and have bent over backwards to not upset my nasty neighbour who lays down her own made-up parking laws about the public space outside her house.
