I'm not sure why you're being down-voted. People driving their own truck for a living are probably not swimming in capital, and outfitting a truck with self-driving capabilities (or buying a new truck) is likely to be expensive. Furthermore, they are more likely to lose out to bigger players who can aggregate inevitable software/sensor upgrade/repair costs across an entire fleet.

The idea that everything will work out because working people can just become capital owners ignores the obvious fact that working people work precisely because they don't have capital.
