When it starts up, choose qualify and then your car. Next choose your track (the one on the left gives the most NP). When you start racing, get up to full speed and run through the fire then stop. Wait until your car blows up and then send your score. You should get about 500 NP for doing almost nothing. You can send your score 3 times a day, so that adds up to 1500 NP per day. Not bad!
