What can be annoying is when you find a place just long enough to take your car, you need to parallel park and you draw alongside the next parked car and want to reverse into the space, some numpty in a mini or something similar drives straight in before you can engage reverse gear. That can lead to a "confrontation." I usually get out of my car to "reason with them in a quiet but firm manner," this usually has the desired effect.
I didn't find the right solution from the internet.
