Yes, Tesla's "Autopilot" seems well named. An autopilot in an aircraft
is not designed to avoid colliding with other aircraft, or solve complex
problems, it just follows a preprogrammed path. Similarly, with current
self-driving cars, you can travel on a highway hands-free, but not a
crowded city street with intersections, and pedestrian crossings.
Decades after autopilots were introduced on commercial aircraft,
"traffic collision avoidance systems" (TCAS) were added. That was a much
harder problem, as avoiding one collision might create another. For
motor vehicles on crowded city streets, it is a much, much, more complex
problem.
To answer David L's question about the motivations of those
proselytizing automated cars, I am sure there are many people who
honestly believe this will make the world a better place. But car
companies are in the business of selling dreams, and a car which will
drive itself is a very appealing dream. In the past there have been cars
with fins like a rocket ship, and many other appealing, but useless,
features. Off-road four wheel drive vehicles now sell well to urban
commuters, even though these are more expensive, less fuel efficient,
and more dangerous than cars designed for urban conditions. What the
commuter is buying is the dream of off-road adventure.
On their own, automated cars would not make an efficient, or effective,
transport system. But it might be a way to get people out of their
privatively owned, underused cars, into public transport. If your car
can drive itself, do you need to "own" it, or have exclusive use? Then
if you want to save money for some trips, would you be willing to share
a ride with others? Welcome to a technology we call the "bus". ;-)
