I'm worried about the implications on the labor market. Here are some quick numbers from the BLS about US employment:
There are 3.664 million motor vehicle operators with an annual mean income of $35,000.
That includes 158,000 transit bus drivers, 500,000 school bus drivers, 170,000 taxi drivers and chauffeurs, 1.6 million tractor-trailer drivers, 777,000 delivery truck drivers and 400,000 driver/sales workers (restaurant take out, newspaper delivery, etc)
By comparison, there are 3.7 million working in all computer and mathematical occupations.
