Scouty wrote You're probably getting 300 rp because your level is probably low. But you should be getting 1 bar in a race. So if you're a low level I would say do crooked cop and keep killing yourself which gives you for sure rp. But do these races when your a high level

Im level 179, thats not low. The race I had gave 3000RP every 20seconds but now it doesnt. Whats your race called?

This race right here. [ Register or Signin to view external links. ]

You start the mission, drive to the military base, and then kill yourself. The tanks will kill you automatically, and you will get around 400 RP every 10 seconds.
