Losing Wanted Level Faster
There are a couple quick ways to have your wanted level drop. One is to go through a Mod Shop. So long as no officer sees you pull in, you will come out with no wanted level. A second way is to switch vehicles. When you first become wanted, the vehicle you are in is reported, so switching cars will help you to elude the police easier. You can also lose cop cars quickly by driving on train tracks, they will not follow you.
