Here you'll find that Murray is in a race in his van versus a bunch of bad guys. If he wins the race by coming in first after three laps around the track, he'll win a key. The way to win this race is to get good at taking the corners and hitting all the nitros. When you get a nitro, try to use them on straightaways so you can maintain control. They're also useful for boosting back up to speed after a tight turn. Be aware that the camera also turns without your input, which can affect the way you drive. That's about all the strategy you need, if you're struggling you'll just need to keep racing until you come in first.
