I learned to drive in the US and always pulled into spaces. Since moving to the UK I almost always back in. The difference is I find it much easier to back into a tight spot (as basically all spots outside of the US are) and then drive out rather than the other way around. For whatever reason backing out of a tight spot is much much harder than backing into it.

That said the wind down here this past weekend, was pretty hellish at times. All my fault though for having a BBQ with the neighbours.
