Nice and slow, is the secret to flow!

Don't waste gas, gradually press the accelerator, pay attention to the oil levels (black and blue), but always prioritize picking up tires. Try to grab 2 or 3 wrench early on (manage them throughout the game) and use them as soon as the body is slightly damaged (don't wait until the last moment to repair). Ah, and try not to crash into anything!

Thats my strategy.
