There are a lot of things you have to worry about when you are parking your car.   Is there enough room for me to park here?   Am I too close to the shopping cart return?   Will somebody try to break into my car if I park here?  Is someone going to park too close to my car and open their door into mine?  Will the ground below my car suddenly give way and cause my car to sink into a pool of water?  Wait…what?
