Re: Autopilots
The difference between autopilots in aircraft and cars is that for the most part, autos move in any direction, and at any speed, in a single plane, with all kinds of obstacles to be avoided[1].
Whereas in aircraft (except around airports) are all moving in the same direction & relative speed at any given altitude, with few obstacles[2].
Autopilots for cars is contraindicated ... unless they are on a separate conduit system than the rest of us. Which ain't gonna happen for local. Might happen for long distance, but probably not before my grand-daughter is married, though (she's a year and a half, or thereabouts).
[1] Cats, dawgs[3], bicycleistotards, iFad wielding pedestrians, impaired drivers, folks from blighty in a left-hand-steer car for the first time (and vice-versa, of course!), mopeds, squids on rice-rockets, suicidal teenagers on skates/blades/boards/razors, the postwo/man, delivery drivers unfamiliar with the area, children not properly stowed by their parents, OAPs with pension check in hand driving their one day per month, and (here in Sonoma, anyway) tourists with blinkers on who aren't looking for anything but The Mission or The Barracks or General Vallejo's house or a specific tasting room ... and etc.
[2] The un-avoidable (bird-strike), and avoidable (weather).
[3] I killed a dawg the other day ... The idiot owner was talking to a friend on a corner. The dawg was on one of those fucking awful retract leads. The dawg spotted a squirrel/bunny/cat/whatever on the other side of the road and took off after it. It bounced off the right side of my front bumper with enough force to pull the idiot owner off her feet. I stopped. So did the Cop who was behind me. The idiot ex-dawg-owner wanted the Cop to arrest me. He declined, telling her that it was her fault, not mine. She complained about her own bruises, "caused by [me]". The Cop said "stupidity "should hurt!", and I went on my way ... If you take anything from this story: If you have a retract lead, throw it away & get a proper lead. Ta.
