Your arguments make no sense. 1. A Tesla with full self-driving hardware can be had today for ~$75k. And the model 3 will cut that in half. And the model after that will be even less. Millions of people can afford this. 2. Who said anything about retrofitting old cars? As far as I know, nobody is planning to do this. 3. This isn't a requirement, and it won't happen all at once. The plumber with an old F150 will continue to drive as he always has until the cost/benefit makes sense for him to upgrade. 4. Self driving tractors move at 3mph, and I don't think farm-field traffic fatalities are the big driver behind automated farming. Different use case.
