They are scattered right on the track and you just have to collect them, racing at high speed along the road. Overtake cars, collect fuel canisters, drive over painted arrows to increase your speed for a while. Beware of racing sports cars. which will appear periodically. There are no rules for them, you have to dodge them, because it is useless to compete with them. Accumulating coins, buy a new car with the best technical parameters in Fuel Rage
