Don't be afraid to ram into your opponent to slow down when recovering from a spin. This is a perfectly legitimate strategy.
Practise
Playing with Opponent's make you bore. Try something new or something you have experienced.
1. You will require connection
2. Open the game.
3. Go to multiplayer.
4. Host your own game.
5. Start a game and let only 1 player come.
6. Play until he gives up and leave between the game.
7. And then it will let you play alone.
Time-Saving
If you find yourself off the track or pointing the wrong way it is sometimes quicker to reset your vehicle instead of manoeuvring yourself back into position. Doing this can often be a time-saving solution when you're stuck.
