Realistically, there's maybe 1,500 of these cars on the roads in the United States at this point. So it's a drop in the bucket. It hasn't hit yet. I have no doubt it will.

Waymo's not the only company that's doing this. There's one called Zoox out of Amazon. They have these very cute little, they look like little beetles that wander around. Tesla, we hear, is also working on this. And then there's some companies in Europe. So Waymo's not the only one. It is expanding and will be appearing in Washington, D.C., Atlanta.

in Miami by next year, presumably, unless the regulatory environment changes. Companies are throwing a lot of money at these things now with a theory that eventually they'll make money at the other side. So we'll see how it all plays out.

Happy to be here. It's been fun.

Back in 2021, streetlights in some cities across the US, at least 30 states are involved, started to suddenly stop being white and start being purple.

which kind of freaked people out but photographers love it and it turns out there's this like all these photographers who are who are kind of chasing around after this mysterious purple glow because they love the kinds of images they get when they photograph under it and as cities are working to change out the lights the photographers are kind of in a race against time to get the shots before this really cool light goes away so it's kind of funny

It is pretty cool looking. Yeah. We have a nice photo gallery in the story and, and also I've got links to some of the photographer's work. It's just, it's cool. So it's not the purple, like a black light. They really are just this kind of strong violet color, which is, is pretty cool looking though. It's in fact not what the Department of Transportation wants or allows.

Streetlights are supposed to be white, so they are busy replacing the bulbs.

So this is kind of fascinating. So if you go back to like the mid 2000s, remember, we had all these sodium vapor streetlights that were kind of weirdly yellow and those had been put in partly as an energy saving method. They were a somewhat newer technology and a lot of people really hated that yellow. And then in the mid 2000s, LEDs got cheap enough that we could have them in streetlights.

And LEDs are great because they save energy, they save money, they last a really long time. So they save even more money because you don't have to replace them very often. So that was all beautiful. But LEDs don't emit white light. What you do is you get LEDs of different colors together. And when they mix, they emit white light, which is pretty much what the sun does.
