I'm trying the obvious approach in replay and I can't seem to be able to do it. I've sat in alleyways and parking garages out of sight for several minutes without losing them, they just circle around until one sees me. I often get stuck and I am not allowed to abandon the car. I tried going to Los Santos Customs but it was closed. The worst part is that Franklin won't shut the f*ck up (shouldn't the guy with special driving powers be driving the car anyway)
Is there any kind of trick to this?
