Speaking as an ex driver, the place should not be in business.
Some of the problems I remember from the cabs were not accelerating on the highway to the point I would drive half a mile down the highway and still be doing 20 with my foot all the way down on the gas which scared the hell out of me every time I merged. There was also a cab with no shocks so when I would hit around 40 miles an hour it would shake every which way.
They also treat the drivers like crap. The cab might make $120 and I would have to pay $125 to rent the cab.
