Stop worrying about people up your rear end lol.
Going head first into a space will eventually result in disaster a the swing needed is alot due to the length of the nose. I always reverse. If people are up your arse. Slow down, stop, reverse lights on and wait till they move. Worry over. My car will catch the smallest kerbs and I've yet to do it in a space.
Take your time and don't panic because of other people. I do the same as stew, or if they don't acknowledge the reverse light I simply plant the foot to board and create some flames for a visual spectacle. They do eventually move and realise what your trying to do.
Just chilax and enjoy the experience
