Do you really believe the current system of flashes was the only system used for the last 40 years? Or that the system was perfectly strict with 1980's technology? These systems were implemented city by city and were not exactly the same. Some of them even used audio or radio instead of strobes. What you describe does…

If you’re turning right, you are crossing TWO crosswalks. _| If you have the green, then the second crosswalk | has a walk signal. If you have the red, the first crosswalk _ has a walk signal. The driver turning right must always watch for pedestrians, regardless of red or green.

@Darth: That’s mostly a myth/legend these days. There used to be some lights long ago where that would work, because they had early, simple detectors for emergency lights to allow police and ambulances through on a green. But since then most cities have moved to more advanced detectors which look for more specific…

I use mine, but only because they didn’t have one without it when I bought the car.

My wife is that way, while I love the automatic lights. Makes things interesting when I borrow her car near dusk. (Why can’t I see? Oh yeah.)

We don’t need to go away from batteries, just go with LiFePO4 or another alternative instead of Lithium Ion. Some EV cars are already doing this.

Why do chargers have names? My first guess was street names where the nearest other charger stations were.

Even when done politely, the “you don’t deserve to be here” attitude still shown through.

This is only stopping it from being sold to new players. They aren’t removing it from users who already have it. (So far.)

Yes, 10,000 is tolerable for unpressurized flight, but 8,000 is much more comfortable to the general public in day-to-day usage.

“Car suffered a low tire pressure. Driver swerved! (slowly and carefully) to the side of the road.”

Thought it was usually 7,000-8,000 ft cabin pressure. 10,000 is a bit rarified.

These are engineering students learning how to accomplish tough challenges in the real world. The process they learn here will influence all they do in the decades to come, in whatever field they are employed.

Mesa managed to pass Mesa for third

10$ for earplugs and muffs is small change compared to actually fixing a track section. Safety theater.

San Bernardino is still in the LA basin, southwest of the mountains.

Diesel which is used for boats or generators can be purchased without the road tax. (untaxed diesel has a red dye, so it’s illegal to use in a road vehicle.)

The 5-10% of usage that needs to use the generator during peak usage doesn’t make the remaining 90% moot.

This is typically happening when the outside air is hot, too. And they already have a door open.
