There is no parking on the street where I live but I regularly park on a side road where street parking is unregulated, about 50 meters from my house. If there is a space I'll park my little car. I'm a good reverse parallel parker as I've always had to park on the street, and my car is small.
One neighbour in particular is infuriated that I park in front of his house and is getting quite nasty, (muttering veiled insults, asking other parking cars loudly if they live in the street - we have had one polite conversation when we shared our opposing points of view and I suggested they campaigned for restricted parking in this street to resolve the issue).
AIBU - I should drive past a legal vacant parking space closest to my home because my neighbour feels entitled to it.
AINBU - it's first come first serve, if you drive past the space the next person will park in it anyway, just because you own a house doesn't mean you own the street.
