Even small light general aviation aircraft such as Cessna 172 have
"Auto pilot". This will maintain a heading and altitude.
http://en.wikipedia.org/wiki/Autopilot
Large civil airliners have "auto land" but it can only cope with
normal fair conditions and isn't an extreme event like car collision
avoidance.

Aircraft collision avoidance is a whole lot of other equipment.

Many boats including sail boats can maintain a course without
intervention. A simple windvane wil do most of the work (until the
wind changes).

None of it has to be "fly by wire".

None of these are completely automated, except, perhaps the auto land.
And, then, only for a relatively simple task compared with driving a
car. Processing all the information about where you are and things going
on around you (like pedestrians and other vehicles) is far more
complicated than you imagine.

Probably a lot closer to 100%. I think a lot of this boils down to people
who want to climb into a car and have it follow a wire imbedded in the road
all the way to their destination, and people who love to drive.
