In my view people need to keep control of the vehicle, learn to back and park and repair everything possible. Otherwise we mortgage our future to those few who have specialized knowledge. And worst of all it endangers our very independence.
While I very much admired Carl Sagan I don't really agree with that assertion.
There really isn't just a precious few who have specialized knowledge: there are legions of them. The skilled tech who can fix your hi-tech washing machine will likely be lost trying to work on the turbocharger in his car. So would a proficient programmer used to dealing in software.
Speaking of cars, back in the 1950s and 1960s you generally needed to work on your own car: they weren't nearly as reliable as today. Not sure I would even classify much of what the "average man" did as knowing the ins and outs of the car. They could change points and plugs, replace a generator or alternator, and a myriad of other things that regularly failed. But rebuild a transmission or engine? Not likely aside from gearheads (who are still around).
In a way technology is just an extension of the centuries old division of labor. Even the westward pioneers of the 19th century couldn't have made it without someone else making nails, wagons, fabric, wire, tools, etc.
