This will help you have a clean record and never waste any impound strikes or get out of jail markers.
When you are being chased by the cops there are times that they will catch you abd you will get busted. When you get caught and they are showing the little clip of them arresting you, press the reset or power button on your xbox and it be like if the race never happend. Then start your game again and now you can know if you need to lower your heat or go at it again witout ever gettign busted.
This also helps because you can raise your bounty a lot higher but the AI will get a bit harder at times, But it's a good way to go out and test your cars if your are trying to figure out wats best for your races or the cops.
Ok if your in a pursuit and you think it's impossible to get away there is. If you go to the baseball stadium (kind of the upper left hand corner) there are two entrances and both entracnes have a pursuit breaker on each side.
So you hit one on the first entrance and then you should hit the brakes but make sure on the other exit you do not hit that pursuit breaker. Then turn around go fast and hit that pursuit breaker. Then you will be trapped inside and no cops can get to you. So wait there until you cooldown all the way. Nut then you have to select jump to safe house because your trapped inside.this has always worked for me if you do it right
