For a good long time standard cars will coexist with self-drivers.
I can easily forsee having at least one of each in my garage. The ordinary one for exactly the reasons you mention. The autonomous one for innocuous trips.
But, the older I get, the more I see an autonomous car as freedom. Someday I will be too old to drive, and so will you. Do you want to live in a nursing home and take their short bus to the mall every Thursday, or do you want to go where you want when you want?
And, how much do you want your insurance to cost? I expect autonomous cars will have very low rates.
Lastly, if you ever get pulled over, do you want an electronic record that can prove you were not speeding, weaving in your lane, etc. or do you want you word against the cop's word?
Police departments are going to be besides themselves without taking in all the money from DUIs if people can just go on auto mode.
Thats true, in theory.
However the plan isn’t to put an AV into your garage. It’s to have companies that own the AVs and timeshare them out as they’re needed. There was a tread here recently on that; about how privately-owned vehicles are only used 5% of the time, while corporately-owned, “timeshared” AVs would push that figure considerably higher.
When that happens you become subject to the whims of the company that actually owns the vehicles.
