I do use parking guard even if i generally do not feel a need for it, and i still say so even if my parked car was dented a few weeks ago and after my parking guard timed out, hence why i use 3 hours now and not 1 hour as i did before.
I use the timer as at home i have CCTV, and when i park out on the town it is mostly just for shopping which i get done with fast.
The fact someone would drive against 1 way traffic, encounter a on coming car and then reverse into my car, and then leave a note only to retrieve it 5 minutes later,,,,,, well i cant account for things like that as that would send me into a tailspin off madness and violence.
Even if i in general safeguard my sanity by think every single person in the world are a raving idiot,,,,, then i do prefer to not get that assumption of mine confirmed, i much rather hope i am wrong with the people i meet in life.
I am very glad that little old lady saw my car getting rammed and took the plate,,,,,, even if she is old guard ( close to 100 YO ) then i still dropped off a fistful of flowers to her. CUZ otherwise i would have been SOL as my dashcam was off.
I must also say it is the first time my car have been damaged when parked,,,, aside for parking lot door dings,,,, which are also bad in its own, but i can handle those as i do not in any way identify with my car.
Actually i just noticed yesterday getting home that my car that had been parked in the field at my friends place, well it seem like again a deer have been headbutting it during the night, and more scratches in the paint have popped up on the driver side of the car.
