I went over that fooking yellow thing the other day, I was not happy as the car went bang on top of it and I could hear them yellow spikes scraping along the bottom.
I decided to leave through the entrance yesterday so I didnt have to go over it.
The GF wasnt happy as she was in the car and the guy in the BMW who I made wait for a extra 20 seconds to get into the car park gave me a funny look. lol
