I genuinely hate leaving the Roady in a public car park, not because i'm worried some idiot will dent it, it's plastic, but because i've lost track of the number of people who can't park and seem to think that they have the right to park over the white line. My car's small so leaves a nice gap either side due to it's size, other drivers seem to think the space can be used by them, problem is I then can't get into the car. I had to almost drag some bint away from sunday lunch in a pub a few weeks back because she'd parked less than 8cm away from my door with 3 clear bays next to the right of her car that had been clear when she 'parked'.
That said I refuse to park like a gimp in two bays. That's just an invitation for someone to do something less than nice to your car.
