Bob and I just had a very scary experience. It's raining crazy hard and everything is very slippery. I was pulling into my usual parking spot (along the side of the road, on the grass, at an angle with my car pointed down) when my brakes decided they didn't want to work very well. I slid almost into a metal pole (part of a sprinkler system). This was with my foot pressed to the floor. I had planned to stop about five feet before it. When I got out (after I made sure my emergency brake was clearly on) I saw that it was merely one to two inches between my bumper and the pole. It's going to be scary getting out of that, for sure.
EDIT: There are muddy skid marks. And it was incredibly hard getting out. My front left tire was in like this huge dip in the grass/mud. Gross.
