Geo-fencing counts, IMO. "Driver assist" does not. Full autonomy respresents an economic paradigm, geo fenced or not. When private cars went mainstream, the economic cascade was so broad that no one could have predicted it. Supermarkets, for example, and the subsequent impact on food industry was a side effect of private cars. Suburbs. Disneyland... Self driving is such a change. Starting from geo-fencing is just a constraint on how fast the change happens. Private cars were limited by affordability instead. There's always something. Once these cars are on (geo-fenced) roads, infrastructure (eg signs) and vehicle can start adapting to eachother. There will be real economic pressures to "open up" roads and highways to autonomous driving. The tech problems in the space are so interesting, we forget about other aspects. Ultimately though, geo-fencing or any other hack could get us to the point where product problems get solved without a 1:1 relationship to solving tech problems.
