Walking is a trendy way to get to where you should have been in the first place. But there are problems keeping it from enjoying truly widespread adoption. The obvious is that things are on average a little too far apart. That could be fixed by growth and shrink rays, if they weren’t all being used for merry pranks. Another problem is the weather. It’s often too cold to walk all the way to the thing. If it isn’t, it might well be too hot. If it’s too hot, there’s a great chance it’s so blisteringly sunny that it’s not nice to be outside. If it isn’t, that might just be because it’s too rainy. Sometimes it’s so blasted medium there’s no going outside.
But one further problem is the risk of collisions. This is mostly colliding with other people walking, or as they are known in the trade “pediatricians”. It’s annoying to collide with, say, a mailbox. But there’s no way to fix that problem except to set the mailboxes somewhere they can’t be walked into. This sets off compensatory problems, though. If we moved the mailboxes up like eight feet so we can just breeze on past them, fine, but then how do we send letters? Do we all just have to go to the second floor? No, that doesn’t work. If we dug pits so the mailbox tops are at ground level? Then we could only mail stuff after kneeling down and standing back up again, and nobody over the age of 35 has time for that.
My solution comes from the car industry, so don’t tell them. Anyway if they want royalties I’m going to tell them my solution comes from experience. You know how hard it is to turn around and go back where you started from without tapping your forehead? There we go. The solution is signalling. This way other people can react to what you figure to do, such as by filing injunctions. We can put a set of signal lights on people walking. These can be hooked up to the pediatricians’ shoulders. If they don’t have shoulders, we can set them on their belts. If they don’t have belts either we can set them on their ankles. If they also don’t have ankles I don’t know what to do. It’s a new technology. There’s always details to work out.
A pediatrician figuring to move towards their left signals their left light, unless they don’t remember left and right reliably. This suggests a side market for henna-rinse tattoos identifying left and right. I leave this market opening for anyone who wants to fill it. It will be hidden in back of the mailbox at the corner. My in back of, not yours.
A pediatrician flashing both left and right lights coming to a halt, or is starting mitosis. Either way people will appreciate the warning. A pediatrician already stopped who signals both lights, and who has already divided into two or more genetically identical daughter selves, is preparing to move again. This will warn people to be ready with cardboard boxes and packing tape. Several short taps on the same side indicate a desire to spin. The left light indicates a spin counterclockwise as viewed from above, right indicating a spin clockwise gain as viewed from above. Unless I have that the other way around. Matters are reversed in the other hemisphere, because it’s different in the Eastern Hemisphere. Also they’re different when two pediatricians are on the sidewalk and the signaller is between the companion and the curb. This part could use some clarification.
A short and then long tap on either light indicates the matching arm is about to be put out. Why, I don’t know. The important thing is being considerate.
I know you all want to shower me with praises and money for fixing walking. There’s no need, although I wouldn’t turn down a $560 million payout if you’ve got it. But I’ll take my reward in being the person who solves the problem of what to do when you’re walking right toward a person, and you can’t agree who moves to which side. Now, we’ll be able to not agree which side to turn to, but we’ll have lights and technology to do it with.
