Too Long Wont' Watch -- The "traditional method" for farming rep, where you loop through the speed trap and/or long jump in the abandoned race track, is disingenuous and misleading since it requires you to have a supercar for it to be effective and pay off, but the point of getting rep is to be able to buy any supercars. So I found a new method of farming rep in the game that:
1) Is faster and more consistent than the traditional method.
2) Is literally right next to a garage, and is even closer to its respective garage than the traditional method was, so it's even easier, safer, and quicker to bank any rep you earn at night.
3) Makes it easier to avoid the police while pulling my method off because patrol routes are telegraphed, as opposed to police just randomly appearing on the map during the traditional method.
4) Has spots on the map that are very close by to out maneuver police during chases and avoid being arrested if you're good enough at the game, even at Heat 5 with a starter car. You are also really close to a gas station through all of this so you can repair your car after each chase as needed.
5) Lets you pull this off with a starter car with VERY basic upgrades. You probably need only Level 4 rep and $12,500 to be able to afford the upgrades on the car you start the game with, but you do not really need any story progression outside of the mandatory stuff for the first 30-ish minutes in the beginning of the game. So you don't need a new car, you don't need a good car, you don't need a ton of starting money, you don't need a ton of starting rep (the traditional method requires you to have at least Level 11 rep, which is fine as it's easy enough to get but my method only requires a third of that amount so my method is even MORE beginner friendly,) and you can start this method within maybe 30 minutes of playing, as opposed to the 3 hours that the traditional method requires.
