I think a lot of people slating the OP have never tried to park a large car in a car park with small spaces.
And I think you are wrong

I'm afraid I have no desire to drive around for ages trying to find a car park with sensibly sized spaces, so on occasion the back of my car will end up in another space like the OP's. I'd much rather it get bumped gently by someone parking than scraped all down the front/side by someone driving around the car park who hasn't noticed that the front of my car is sticking out more than the other cars.
Just because we chose to drive large cars doesn't mean we are entitled to take more than one parking space in order to park them. In 8 years of driving 5 Series BMW's I have never once had somebody clip the front of it because I was overhanging the front of a space too much - it's just not an issue.
