1) If you're in a monster truck, you're going to be able to roll over stuff. A wall of tires would not stop such large wheels dead in their tracks, let alone damage the vehicle. Nor would what looks like a curb.
2) Taking car models of any cars, including sports cars and putting 4 fat tires over them is a really poor excuse of "an off road car".
3) A porsche cayenne that's quite fast and powerful for what it is can only reach a top speed of 10 miles per hour hm?
...And it's a crappy copy of other much better, more difficult parking games. Seriously, the car doesn't even turn as if it has wheels. The turning circle just doesn't match up.
