I used to have corrective glasses that did what he described. I can't remember what the type of lens was called, and Google is being unhelpful. But walking in and out of shade was definitely a bit annoying because it kept repolarizing.
> ✗ Moving sidewalks (do airport conveyors count?)
I'd say so. Open question: how would we put benches on moving sidewalks?
P.S. I am amused you didn't include hovercars.
- pserwylo 13y agoI recently read an interesting New Scientist article in an old (2009) magazine[0] which explains how to use moving sidewalks for mass public transit. Spoiler alert - it has actually been done before!

- saraid216 13y agoI guess making the sidewalks a circular deal would make the benches problem pretty easy to solve. I was really more hoping for some scheme to expand and collapse the benches.

- speeder 13y agoHere in Sao Paulo there is a moving sidewalk connecting two major metro stations, it is really cool for most part, but sometimes shit happens, like when one asshole decide to stop at its exit, or when someone fall, or when it breaks.
- olalonde 13y agoThere are also lots of those in Hong Kong and Shenzhen, though most of them are indoors.
