I am so smitten with mine, that I will not use it if I don't know where it will be parked! LOL!
I do exactly the same as Scribe, find the empty part of the car park, even if it means having to walk some distance.
At the moment I am having to leave it outside, which I am not happy about! It is relatively safe on the drive but I much prefer to have it in the garage. However if the car is wet, I do not put it in the garage.
