Don't want an unsightly parking garage mucking up your downtown? No problem, just put it underground. But that takes up a lot of space too. Not to mention the amount of the city that has to be dug up. Here is a crazy European solution that attempts to minimize the footprint while maximizing the amount of cars stored. Neat idea but considering the trouble that I have had with machines in parking garages, I am not so sure. On two occasions I had a parking garage machine tell me I owed over $10,000! I can only imagine what this place would charge me.
