These car parking towers are pretty cool!
You drive in, over a turn table,
Park your car in a gondola style lift
Get out of the car
And then watch as the car is moved up on the chain into the tower!
All the gondolas are connected in a big loop so when you want your car back they just keep the machine running till your car comes around.
You drive out backwards on to the turn table, your spin right round, and off you go!
