IMHO it's fun to think about the economics of autonomous vehicles. For example, here's a neat article on "second order effects" of electric and autonomous cars [1]. (examples: Increased use of autonomous cars could mean less space lost to parking lots in cities. Higher utilization for cars could mean faster turnover (~3 years/car instead of ~10).)

One thing to think about: autonomous cars might make a big difference for car-sharing services or trucking, but they're less essential when you're driving the car yourself and parking in your garage. I think traditional cars will be around for a while. (Particularly in lower-density areas where there's less demand for ride-sharing services.) This article [2] suggests regular cars may be around until 2050 or so:

"According to IHS, a firm that provides automotive forecasts and insights, sales of autonomous cars, including driver control, will begin by 2025 and could reach 11.8 million in 2035; sometime after 2050, says IHS, almost all vehicles will be autonomous."

So your hobby is probably good for another 30 years at least?
