Uber South Africa dies not care

Why does Uber South Africa allow trios to be transferred between cars/drivers ? (Perhaps because they charge higher fee and provide lower grade car ?) Why does Uber South Africa allow old cars to be used which has a maximum speed of 100km/h ? (Perhaps because problem with wheel balancing becomes evident at speed higher than 100 kmh) Why do Uber South Africa allow Uber drivers to drive with shoulder less shirt (Perhaps because Uber don’t care and does not set standard)
