Public transit doesn't scale outside of dense urban areas. North America doesn't have the population density to make public transit viable outside specific metros like Chicago, NYC, Boston, DC. And said metros already do have public transit. So cars are the main viable option, and self-driving cars present the opportunity to regain time lost to commuting. Less discussed, but probably even more important are driverless trucks. There's actually a shortage of truck drivers in the US, since it's a job with pretty bad work life balance and unpredictable hours. Self driving trucks could potentially be huge in terms of improving freight costs.
