Most of the crap charges levied against air cars (not safe disruptive,
unsightly, eco adverse, security risk ala 9-11) are the same charges levels
against automobiles by people who hate the fact that the auto underpins a
real expansion of the freedoms and horizons of the common folk.

If air cars happen they will grow slowly and an appropriate system of checks
and balances will emerge. Until then ponder this...

Air cars, when operational, shall be no less safe that any other mode of
transport. Ships sink. Cars and planes crash. Trains derail. Balloons
pop. Amish people get kicked, bit and thrown by their horses. All of these
things can be fatal. If they scare you exercise you individual right not to
use them. Do not deprive the rest of us of freedom in order to satisfy your
cravings.

Unsightly is a personal opinion. Everybody has there own opinions.

Environmentalism is an ideology on par with Nazism. It deserves no
comment.

Security is an issue only if we let become one. Technology gives more as
many advantages as disadvantages, and real security is rather simple. If
armed air marshals were available on 9-11 the towers would still be there.
