I once made the mistake of renting one of those cars, putting my backpack and some groceries behind me, and driving straight onto a freeway. This absolute sh*tbox was beeping so loud I was afraid for my hearing. I drove some 10 miles like this before I could pull over and move the things. I'd not set foot in one of those cars ever again (same goes for Lexus). I was dreaming of really bad things happening to people who thought it was a good idea to emit series of very loud beeps while the car is driving.
