I've always been lucky in that I find parking relatively straightforward, not sure if you call it good spatial awareness or whatever. Where possible, I will reverse into a space so I can drive out when leaving. And I always do my best to ensure enough space is left for the adjoining cars although not always easy these days i.e. larger cars, tighter spaces. However I notice quite a few people drive in to a space but then struggle when reversing out, especially if the car park spaces are tight and their car is on the larger side. I'm not sure if they're not confident to reverse in or simply find it more convenient to just drive in.
Parallel parking is also something I'm not bad at, although I'm not immune to having to drive out and give it a second go!
How would you judge your own parking skills? Are there any aspects of it you struggle more with?
