I didn't even take the insurance monitor they offered because the difference in cost turned out to be something stupidly low (like a saving of $1/month, or similar).
I don't want my car monitored, I don't want my movements monitored, and I certainly don't want my car reliant on the continuing goodwill of some upstream provider.
They need to sort out the software and privacy implications before I'm biting, especially as my personal accident history beats current SDV anyway: over a million kilometers with a single accident.
Most drivers take absurd risks that negate any possible skill advantage.
The last 20% will be tough. There are 1.3b vehicules in the world, most of the aren't in the US, most places will need a complete infrastructure revamp before autonomous cars can even dream to drive there
