To be fair those bays are small and that would fill a bay and overlap, meaning any car parking next to it would no doubt smash there door into it, so you can hardly blame the guy.
If parking bays were bigger or people had a lot more respect for other peoples property than people with nice cars or wider cars would not feel the need to park defensively.
I personally always go and look for a nice space as generally there is always an edge or end space or just park very far away across two.
I have to admit I am still not keen on new shape, much prefer my classic Vantage from both front and rear.
