Comment Blood sugar and eyeballs (Score 2) 20

Apparently your blue sensing photoreceptors in your eye are super sensitive to blood sugar, and you could do a blood sugar test with a color calibrated phone app having people compare two shades of blue side by side. If you can't tell them apart, your blood sugar meets/exceeds/is below a certain threshold. It's not hyper accurate but useful for diabetics.

Comment Re:I don't live in California but... (Score 1, Informative) 244

In our neighborhood all the kids (who look like they weigh about 75 lbs, so about 2x the hp/weight ratio of an adult) have these borderline dirt bike looking things and they're constantly doing the "ride doing a wheelie for 500' in a mostly straight line" except when they wipe out and slide into oncoming traffic. A couple of kids this year have already gone to the hospital in my area for that sort of thing. I dunno how fast they can go but seems like at least 30mph with tweaks which is street legal scooter territory. Ebikes are nice because there's no license or registration so the cost is low, but they're commuting 3-5 miles each way 5 days a week on public roads, so they're definitely part of normal traffic, and they're absolutely getting in a ton of very messy accidents.

The disorientation goes away for most people after ~1-2 weeks, but yeah, you have to be really committed to the product. I am very resistant to motion sickness but I recall a couple times in the first month where I was in some ultralight airplane sim (like pilotwings type thing) and looking down while banking sharply and almost threw up.
 
Mass consumer VR is a fucking dumb idea though, I'm stunned apple was still shipping hardware updates, they must have contracted for a million of the displays or something and were hoping they could limp across the finish line without sending too many off to the landfill.

Side mirrors almost always leave a large blind spot directly behind and close to the vehicle. There's a reason that when firefighters are reversing their appliances they always have at least one of the crew physically get out and watch the area behind the vehicle.

Even a rear window and rear view mirror almost always leave a significant blind spot low and close behind the vehicle, which is why reversing cameras became a thing. When they're done well, they really are significantly safer, as well as sometimes making it a lot more reliable for most people to park the vehicle in difficult spaces.

One of the modern innovations I really would like to have is full AR on my windscreen. I want unexpected hazards highlighted in real time, particularly those that are more easily detectable by non-visual sensors, like big potholes or animals obscured by vegetation near the side of a country road. I want the actual driving line I need to take to follow my planned route through complex junctions overlaid slightly on my view of the road ahead. I want light amplification for night driving, ideally combined with some other technology that can reduce the glare from oncoming headlights to prevent dazzle.

Although I only want all of this if (a) it's implemented well and (b) any additional data it uses is reliably up-to-date and (c) there's an emergency shut-off that instantly clears everything off the windscreen in case anything goes wrong.

We don't need tech to replace something that works better than the tech.

Oh, don't be silly. Next you'll be making even more absurd claims, like that car theft was already a solved problem 20 years ago thanks to immobilisers, or that having separate physical controls for essential functions that you can find and use without taking your eyes off the road for several seconds to mess around with a touchscreen is safer, or that no-one ever hacked 100,000 cars at once from 1,000 miles away back when they didn't have always-on remote connectivity and allow OTA updates to their essential control systems.
