please can we have some kind of taxi% category

nms

that already exists, NMS and MS, you can use taxis in those categories.

taxi%? what would that entail even, theres no taxi minigame in gta 5

Private fare%. Acquire Downtown Cab Co. and complete a private fare

I think that would not be really interesting sience it is random when you get the phone call for the private fare and you can wait for more than half an hour
