Calm down. They never said anything about the two things happening on the same device.

I get what you’re saying — so it’s about the subconscious awareness of the state change that happens after the driver decided to go, but before the car starts moving. I can see some amount of value in that.

I still can’t help but think it’s going to be interpreted by many as a sign that it’s safe to proceed and ignore the car rather than be prepared for any eventuality, though.

But isn’t that exactly the situation we’re in now? If there’s a car in the opposing left turn lane, they might start to turn in front of you.

The only thing the light does is say “right now, they’re braking”. It doesn’t say whether they’re moving or stationary any more than the headlights, and it doesn’t say anything about their intentions or whether it’s safe to enter the intersection.

Yeah, the only thing I could think of is that I’m driving down a country road, and I see the front brake light ahead of me because someone stopped for a deer in the road or something.

Otherwise I cannot fathom what benefit it brings. Anything that ultimately becomes “if you see this light, it’s safe to [X] in front of this vehicle” is going to get people killed.

And the negative state of “the lack of this light means that the vehicle could be moving” is exactly what we have now.

I don’t understand this at all. Why do I, as a person in front of a vehicle, care whether or not it’s braking?

Thanks for the explanation. Ironically this was the bit I didn’t know:

In modern times, USB keyboards are periodically actively polled instead.

I was thinking the implication was that some computer had faulty interrupt handling that would smash the status register or something.

Honestly I think I’m just too old to understand memes.

I feel like I should understand this, but I don’t.
