While driving less than 5mph in a parking garage up a fairly steep incline, my car started to well, buck is the only word that comes to mind. Jumping back and forth from drive to reverse or it felt like. I was too busy hanging on to the steering wheel to look. I was particularly terrified as I was approaching a 2 foot high concrete wall with a 4 story drop on the other side. I read a post here about weird stuff happening at low speeds on inclines. Anyone else?
