Mohammed

Mohammad is a Middle Eastern taxi driver, apparently in his late thirties, employed under Roman Bellic; Roman is shouting to him over the radio in an early cutscene, but he first appears as the one who drives Niko Bellic around when Niko receives free taxi rides (Roman's friendship ability). Early in the game, he picks Niko up in one of Roman's Esperanto taxis, but the fleet is upgraded to using Cavalcades right after Roman buys a new safehouse in Algonquin -- a phone call from Roman suggests that he had had a sizeable gambling win around the same time. Mohammad is invariably rude, and resents not only Roman for his company's perceived low wages, but also Niko ("dog lover", in Mohammad's parlance), who he believes is a lazy freeloader for getting free rides (Mohammed mentions he is not paid for these trips).

Mohammad claims that he only remains a taxi driver to seduce the women he picks up; he says he loves his wife, although evidently he feels no need to remain physically faithful. He suggests that he has six kids -- his wife has had none, but he estimates that with all his adulterous activity, he probably has around that number. The truthfulness of his boasting is left to the player's own conclusions.

You can kill Mohammad any time, but he'll always come back.
