Have you ever considered something alternative to air inflated tires? Have you seen some of these alternatives that have essentially spaces in between the upper wall and the wheel? Have you thought about that? Yeah, we haven't found a tire that... Because you got to worry about road noise, you got to take out potholes and bumps, you got to have like good grip, but you also want to have low rolling resistance so that you get good range. Those are a lot of things to try to put into one tire. Then if you also say, and it can't have air, it's like this is hard. But you're talking, I'm talking to a guy who's putting people on Mars. You can't figure out an airless tire? It's an incremental constraint. I'm not saying there won't be such a thing. I think there will be, to be precise. Because it seems like we've just gotten way too comfortable with this idea that tires blow out. And you get flats. It's very annoying. Flats are annoying. Very annoying. Non-sport tires, by the way, are much less likely to have flats. Sure, they're more bounce. Yeah, let's say you hit at the edge of a pothole. If you've got more rubber wall, you've got a longer way to go before you pinch the tire. So sport tires tend to have more flats, especially in LA potholes. That's the worst. There's one particular pothole on Sunset Boulevard. It would just take out so many monoliths like a boom, boom, both sides of the car. Really? Damn. Yeah, Steven Spielberg was actually once. It's like, hey, Steven Spielberg is like, two tires went out. It's like, God damn it, I know that pothole. I feel like you can pay to fix that. Fix that pothole. It seems like that's actually, it would be like, man, there sure are a lot of taxes in California. Yeah, I'm not sure if a road is this bad. The place is a mess. So ultimately, one day, that's a possibility of having some sort of an airless tire. Because I've seen prototypes. I've never seen one on an actual car in physical, in real life. Yeah, I think the technology is gradually getting there. And I think for something like a robot taxi where you want to have the tires last for a long time and not go flat, it's going to make a lot of sense. But other than that, essentially, most of what we saw in the demo is the same. It's still going to have, now, there was the issue with the glass when it accidentally shattered. How annoying was that? That was shocking. We literally spent hours beforehand with lots of people throwing steel balls at the window. Right. I mean, we must have thrown at least a dozen people must have thrown steel balls at the same window, though. Yeah, same damn window. Isn't that the problem? Yeah, it turns out that might be the problem. If you keep throwing steel balls, eventually it's going to break. I did ask Frans to really wind up and give it all. You know, actually, we should have like, oh, take it easy. Give me a fake wind up. We don't need the fastball. I did ask for the fastball. I'm like, OK, let's go for the slightly slower ball. Do you think it was because you guys were hitting the sidewall with a sledgehammer first? Yeah, that could be. Like, we're trying to figure out how the hell this thing break, because we were just bouncing steel balls off it all day. And we think possibly what might have happened there was that hitting it with a sledgehammer might have cracked the base of it. And once you crack the base of it, it loses all its strength. And then it would just have a hairline fracture. And then you hit it anywhere it's going to shatter. Did you recreate that? We didn't. It's also hard with test glass. Like, when you actually do production glass, it's much more robust than demo glass. Because production glass, you have to have like, massive glass. There's tons of tools and ovens and everything to make the production glass. And if you don't, that takes a while to do. So production glass is always better than demo glass. Nonetheless, it should have worked. And it was probably because we racked it with a sledgehammer and then threw the steel ball at it. But it will be bulletproof to a handgun. Now why did you decide to do all that? Make it bulletproof and make it like you could hit it with a sledgehammer. Like, what was the motivation to make it different than just like a Model S? I mean, I think, you know, it's like, what's cool about a truck? Trucks are tough. And like, OK, what's tougher than a truck? A tank. What about a tank from the future? OK. Now you have a tank from the future. OK. Yeah. That's bulletproof. Yeah. And how's that compared to, you know, way tougher than a regular truck? Like, it's fucking cool. Yeah. There's no desert. I mean, having something that's bulletproof. Yeah, I mean, having something that's bulletproof. That's shit. It's really like Halo with a rocket launcher in the back. Have you thought about doing something like that? Somebody's going to do it for sure. For military use? Yeah. Seems like it. I mean, I don't know. That sounds like it'd be fun. I mean, you should like, you know, cruising around the field and like, just lobbing, shooting rockets. Now, is there ever a possibility that these things are going to be solar powered? Is that some day, is the solar technology going to get to a point where? It's kind of a surface area issue. So I mean, I think we could possibly put the cover of the truck bed, you know, put some solar cells in that. So if you just leave it out in the sun, you know, probably recharges a few miles a day type of thing. It would only be a few miles. But what about one day? Is it possible that technology could evolve to the point where they could extract more? No. Really? No, it's so there's about one kilowatt per square meter of solar energy and then you're going to get probably 20, 25 percent efficiency. So you got 200 watts per square meter. And then that's assuming that you're normal to the sun. So you know, like you're, you know, at the right angles, basically like, are you facing the sun or not? So you know, when you add all those things up, you say, how many square meters can you really get? And then how many watt hours per mile? So it is basically if you could do 10 miles a day, you'd be lucky. Really? Yeah. And that's not going to change. No. Catch new episodes of the Joe Rogan Experience for free only on Spotify.
