We live in a house with a shared driveway. The driveway is gated and we and our neighbours all have a key. Lately, a car keeps parking in front of the gate blocking access so noone can get in or out. It is driving me NUTS, but as far as my online search goes, there isn't much that we can do about it. It's not a police matter as far as I can work out. Anyone got any suggestions of what to do? Or should I just let it go and park in the street?
