The liability argument is facile and naive.
If it were true, cars would be more expensive than airplanes. You all
know those statistics about safety of air travel versus cars. (Yeah,
I'm a lawyer; but I don't handle airplane crashes (not very many) but
as for car wrecks...

Not true. There is MUCH more precedent in the legal system for car crashes.
If I have a one car crash because I failed to negotiate a curve, chances are
I'm not going to get to far in a lawsuit. If I crash my plane because I
wasn't paying attention to my airspeed on final, I get to sue the makers of
the CD-player in my panel. Again...jurors know how to drive cars.....and
only rich people with too much money (that should be shared) fly
airplanes.... blyak.....I feel grimy just typing it
