Yes, and if you are ordering it you can order the size you need for each trip.
A single seater with baggage space for a trip to the supermarket, or a 4 or 6 seater for a family trip to the restaurant, and no designated driver needed...:^)
It used to be that cars were marketed with higher horsepower, torque, lower 0 to 60, etc.
Now they're marketed with WiFi, GPS, individually heated seats, rear DVD/iPod players, etc.
I think that a good number of people will want to purchase their own driverless vehicles so they can make sure it has all the goodies they want. Some driverless cars might have hot tubs, seats that recline into beds, windows replaced with screens that can show what's outside or whatever the owner would prefer to see, etc.
These folks will definitely want to set the computer to "Save my ass first" mode. They might also put it in "violate the law when there are no cameras looking" mode as well.
