My Flying Car
I remembered to add "Go looking for those white science-y books I borrowed from the library a lot as a kid; you know, the ones about robots, or future cities, and such. Maybe by Osborne?" to my TODO list today. And unlike the last time, I found one!
The Usborne Book of the Future, by Kenneth Gatland, illustrated by David Jefferis, Usborne Publishing, 1979.
Even better, found scans of the whole thing online. Skimming through it, I vividly remember pretty much every page. Wow.
Apparently, this book taught me everything I know. I'm sure I sailed through many classes in elementary school simply by regurgitating what I'd learned from it.
