Inefficient parking
This means there often isn't enough parking for all the cars of a house, so a lot of people park on the road.
This means that on-road parking is scarce, and so we all try and use it efficiently.
Our house has a parking space outside easily large enough for three cars:
| AAAAAAAA | BBBBBBBB | CCCCCCCC |It's infuriating when, if there aren't any cars parked there, for the next car to park like this:
| AAAA--------BBBBB | CCCCCCC |This means that 3 possible spaces has been reduced to 2, a 30% reduction in capacity.
Whenever I get the chance, I park my car in the middle space, thus ensuring maximal use.
If I come up to a larger empty row, I'll always park tight up against one of the ends, maximising as much as I can.
