Taxi Driving is surprisingly good money, but frankly events and copwork are, at the moment, the only efficient methods of income.
Hopefully in RS4 criminals will have
more ways to make money, meaning that we won't have the imfamous "cycle" anymore.
P.S.
If anyone doesn't know what that is, its where a gang/group runs out of money, and then goes as cops for awhile to make money. They then stop and spend it all on guns in a giant war or whatever else. They then go back to being cops when they run out of money. I'm personally about halfway through my funds in the criminal part of the cycle, but perhaps I will not have to switch back to copwork after I'm done with RS4 on the way.
