1. If you have the chance to park at the end of a row, do you make sure you are right at the end? It is amazing how many people just park, without thinking about the 1m/2m at the end they haven't taken, perhaps totally oblivious this is having a concertina effect on the rest of the line.

2. If you can only just fit in the only space available, would you go in it? By only just fit, I mean a space that is only about 2 feet/0.6m longer than your own car. This of course has an impact on the cars either side of you to leave their spaces.
