FYI, car park = parking lot or parking garage. Parking lots and garages are easy. Follow the arrows and the "Park" and "Exit" signs and look out for the other idiots who aren't following the arrows and signs.
Oh, yes, exit = way out. While looking for a subway (tube) exit in London, I kept seeing signs reading "Way Out" and couldn't help wondering how far out the English version of our common language had become. Then there is "Mind the Gap" (watch your step when getting on or off the train).
