The main 3 main things you should be careful of when you are playing Bumper Cars are:
*Mine- They do 20 damage to your car. That is a lot!
*Dead Cars- Crashing into them will make you lose HP!
*Walls- Crashing into walls will make you lose 5 HP!
Specials
*Petrol- This will make you go around in circles.
*Turbo- This will make you move fast. Does more damage when you move faster.
*Shield- This will protect you for a period of time.
*Mine- Takes 20 damage
Special Tips
*If your opponent’s car is right next to the wall hit the car to the wall so they don’t only lose HP for being hit but they also lose HP for crashing into the wall!
*Position yourself right next to the wall. When your opponent is about to hit you move away and most likely your opponent will crash into the wall.
*If there is a mine go near it and use the same strategy used for the above tip and your opponent could past thought the mine.
*If it is just you against someone else on 1 player go behind a dead car and stay an inch (or a centimeter) away from the dead car. The dumb computer car will just charge at you at no cost. Since there is a dead car in the way it will not hit you but instead it will hit the dead car. And if you stayed right behind the dead car and your opponent hit the dead car the dead car would have had impact and some of the impact would go on you. This way you can save some HP. It might take time though. – Jonas Suh
