I'm thinking very very stupid. No sprues for casting.

Agreed. This is all stuff that at MOST should be accessible over the LAN. The ESP32 is cheap and provides the WiFi and enough power to run a simple RESTful web app. If I actually need/want to access it remotely, it'll be through a well protected integrated web servie on a jump box.

A cheaper manufacturer could probably make the ESP32 do double duty as the primary micro-controller with a suitable interrupt routine.

Considering that for the one-time investment of $150 and a half hour of your time you could not have to do that any more? Hell yes, you're crazy.

Samsung is collection of several companies and if you've ever spent any time working with them you quickly realize that they all prioritize other Samsung companies below other customers. I don't know whether it's because of anti-trust concerns, or market strategy, or just rivalry, but I've never seen any Samsung company that operated any differently. I worked quite a bit with Samsung Mobile and S.LSI, who are even quite interdependent (though S.LSI depends more on Samsung Mobile than the reverse), and they constantly ignored and even dissed one another.

There's no way your driver's ed class failed to mention that traffic is required to stop for school buses with their red lights flashing, and I think it's unlikely that your written test failed to include a question about school zone and school bus rules. Mine (Utah) certainly did.

In rural areas, like where I live, there aren't any marked crossings, and there really isn't any reasonable place to put them. If you mark a crossing it would only ever be used by the one or two houses near it, and only by school children, because there's really no need for anyone to walk across the street otherwise. The school buses stop directly in front of each child's house. There aren't any locations where a bus could pick up multiple children without making them have to walk an unreasonable distance, so each kid's house is a stop.

Also, the speed limit on my road is 45 mph, and cars routinely drive 55 mph... so having the "huge yellow beast" with flashing red lights and a flipped-out, flashing red stop sign is definitely necessary.

The situation was worse than I thought. According to the AAIB report, they tested the material and found the glass transition temperature to be about 53C, so the jackass printed it in PLA.

Also, since it's Poly Lactic Acid, our metabolism is already well equipped to deal with the breakdown product.

It's great for things that will be indoors at room temperature. I made a snap-on camera mount for my monitor that has held up great. But if it was a dash mount, it would need to be PETG or CF-PA6 to not sag in the summer.

Getting their jobs sent to American AI won't be noticeably better for American workers than getting their jobs sent to Chinese AIs.

According to an AAIB Field Investigation report (pg. 4), two samples from the intake were tested and found to have a glass transition temperature of 54.0C and 52.8C

So some idiot printed them in PLA. PLA is great but is very much NOT temperature resistant. It has been known to sag in a hot car.

Now look at the ratio of human driven cars vs. Waymo cars.

The problem was using a cheap substitute part. I'm guessing an injection molded ABS part would also have failed in that scenario.

CF-ABS is NOT like fiberglass at all. The CF is chopped into fine bits. They lend some stiffness at room temperature but not strength to the part. Certainly the carbon fiber bits don't lend any heat resistance.

Yep. CAFE-style regulation is the wrong way to attempt to reduce carbon emissions. The right way is to impose a carbon tax, then let consumers vote with their wallets and engineers work to make the right tradeoffs to meet customer demand. My guess is that consumers would choose to buy the more fuel-efficient vehicles and engineers might make the same tradeoffs... but now it would be clear that those tradeoffs are worthwhile.

Gas is pretty much exactly at its long-term, inflation-adjusted average price, and right where it was in the 1950s. Since then, it was a little higher in the 70s, a little lower in the 90s, a little higher in the early 2000s, but we're now back at the long-term normal price.

See https://afdc.energy.gov/data/1...

Whether the normal price of gas is "cheap" or "expensive" depends on your income and lifestyle, I'd think.
