This movie is not Gore or Horror.
It stars a cab driver that cruises the city picking up all sorts of customers and doing is job as it is. I don’t know why but I always think it happens in Detroit although it could be in any other city. The driver is a really humble quiet guy that doesn’t talk much and the city portraied is really violent with a lot of night scenes and weird people that yell at each other while being driven to their destinations. The driver is poor, badly paid for is services and the works lots of hours per day, portraing a lonely man in his 40’s living in an urban hell. I know this film is based on a book that is not popular at all.
In one scene he has to drive a pregnant woman to Hospital that yells at her husband the whole time, I think the couple is black although I am not 100% sure about it.
I have seen it in TV; I would say it is from late 80’s or earlier 90’s; The actor is not famous whatsoever;
