I will take 2 spaces when there are plenty, but Ill NEVER take a disabled space. Anyway, what I hate is when you park correctly (for example at the end of a row) and you park so far over that the passenger side is very close to the wall (not a chance of opening the door) so that you give loads of room for the person next you to to open their door fully without touching your car, only to find when you get back, they have parked over the white line into your space just because they are crap!!
Just face it - parking your car in a car park you will get someone who doesnt have respect for your pride and joy parking next to you - no matter what you do. People are like sheep, you park on your own - someone will have to be next to you.
But, given that, I still park far away, but Ill never circle a car park to find the best space, I dont mind the walk.
