Fear of change and new things. People were opposed to cars when they were first introduced. Ironically self-driving cars will arguably save countless lives. The resistance and fear will pass. But I do love driving...
And while its not directly comparable, I still see horse and buggy carriages on public roads in PA so they haven't ever outright banned that particular obsoleted mode of transport. If the Amish lobby can keep shit getting dropped in my streets I'm sure the collective car enthusiasts of the world will keep their right to drive for a while at least.
