This isn't a bumper car, so try to avoid being hit or running into any obstacle. The car you're driving down the road is quite fragile. If it gets hit even once by an obstacle of any kind, it will be destroyed and you'll blow up along with it. Unfortunately, the steering wheel of the car is stuck, so you can't change its direction on the road to avoid obstacles. Instead, you'll need to rely on the super jump feature of your car that you can activate by tapping the screen.
