Been there boys, the passenger side I'd like to bore a hole through the floor!!!!It took me two times till I learned to The first was a hot coffee, in the passenger side hit the corner and she flips out and stays closed although the coffee was spraying out the vent hole pretty good, I almost got in an accident as I had just vaccumed and cleaned everything.. The next time the cup exploded and coffee was everywhere, I have never put a thing in there again.. I gues the moral of the story is avoid the small one or drive slower.. LOL
