My son-in-law thinks that these vehicles are decades away, not years away. He believes that while they might be 95 percent there within a few years, all the exceptions to the general rules that a human being driving a car adjusts to, will be terribly hard to overcome with technology.
For my part, I think that technology development is now moving so fast that solutions will be found. I think it will be five to 10 years max!
Stay tuned for either government intervention to stop the fielding of these vehicles; legal action to stop them; or for all the technology to be developed and my next and final car may be autonomous.
