If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Here's another cool 3d parking game, and in this one you get to be a taxi driver. Across 18 interesting levels, you get to find and pick up peoplel that need a drive. Sometimes even few of them, when they share a cab.
First find the people, then locate the delivery place and get them there as fast as possible. Avoid obstacles and try not to hit anything, have fun along the way.
