taxi caps fixed for mp?

I noticed when I do MP and patrol the taxi's that plague single story mode aren't frkin everywhere when in a private or any online match for that matter. Was there a fix they put it that or has it always been like that. It get's so annoying and boring when patrolling in single player story mode with almost every car being a taxi or same care repeatedly.. and I do have the taxi cap traffic flow installed as well but even before that online had less taxis and better random vehicles
