Step 2: 2. Drive responsively
Maybe sound like grandpa drives, but this way, you'll save gas, and you won't emmit so much gases, and car's parts won't get worn so fast. Doing burnouts, heavy stops, and heavy starts, you're losing money without realizing.
If you want to race, go to a circuit, with a few friends, and race there, there's no speed limit, and i'm sure, you'll have a great time playing with your car with your friends. And a day of action with your car, doesn't matter if you emmit gases, worn parts or waste money, beacuse is only a day, a fun day, as a beach day or something, not an every day drive :P
