Having a full-time driver on retainer 24x7 is not cost effective, but using one a few times a year might well be.

For an 8 hour drive? Still not true, especially with a limo.

Neither is a Google car, though. Adding self-driving requires five figures, probably even in production.

I think $10,000 is a big over-estimate, but even that would be spread out over the life of the car. I'd happily pay $1000 a year to not have to worry about driving.

I'd happily pay $1000 a year for a car that doesn't drive itself.

A limo with a driver is always going to be fairly expensive. A self-driving car should come down in price a lot faster.
