“At least one person has been killed after heavy fog caused a pile-up of over 200 vehicles near the city of Zhengzhou, in central China.”

Heavy fog is no joke. Gets to a point of guessing what is in front.

Ban self driving vehicles

Ironically, most self driving cars use LiDAR so fog wouldn’t affect them. Only Tesla relies solely on optics.

Edit: to stop the pedantics below, water vapor in the air can affect LiDAR, it still functions though and considerably better than a human or an optical camera in fog.

Au contraire - self driving cars have the possibility of “talking” to one another and “knowing” where the other cars are even if visibility is bad …

I remember we were driving through a very foggy part on a highway when i was a child. We already saw crashed cars and many standing on the hard shoulder. Then someone was crossing the highway on foot, so my mother had to swerwe, crashing into another car standing on the hard shoulder.

Don't drive there, and don't walk on fucking highways when nobody sees shit. Stay behind the crash barriers, because you ain't safe anywhere there, even in a car

(Edit: Tbf maybe the person might just have escaped from their own crashed car... idk. But my mother should've been wiser and we should have stopped earlier.)

Lidar really doesn't work any better than regular cameras in foggy conditions. You would need radar for that.

that is baloney.

>possibility

Yeah, and it's basically dead. No one does it and they've started using the bandwidth spectrum set aside for other things iirc

>downvoting the comment that's right

Never change, reddit.

It seems like everything in China is scaled up.

That’s cause he’s wrong. LiDAR is less effective when there is water (in this case vapor) to scatter the lasers but it’s way better than an optical camera and in turn way better than an eyeball.

You need to know the stopping distance of your vehicle on various surfaces, and travel at a speed that allows you to come to a complete stop within the limits of your visibility. Hoping there is nothing in front of the car and continuing on at 60mph is how selfish people cause fatalities.

Wow and I thought the ones we have right down the road were terrible.(I41 WI)

It has so many advantages. Its bound to Happen. Fir example, if there is a major accident a mile ahead, your car will know and Look for an alternative path. A pothole ahead, all cars will avoid it.

Some lidar solutions can work better than others. But in my experience most automotive lidar solutions still have issues in foggy and dusty conditions.

Probably covid related

I was on the last 4 hour leg of a long road trip and driving back home in the middle of the night, suddenly stuck in the densest fog I’ve ever seen. I knew a toll was coming up at some point but I couldn’t see any signs or other cars until I was nearly on top of them. Nearly split my knuckles open from gripping the wheel so hard.

Yeah, it couldn’t have been the heavy fog. Everyone knows viruses cause way more collisions than traffic and weather conditions. /s

Great who is going to clean up all the broken plastic and cheap metal carnage everywhere.

But but the Great Elon told me that for the low low price of 15,000 USD, my car would drive itself (one day soon, definitely, like next year probably, if inky we didn't have all those pesky government regulators) , and just like people, all it needs are some cameras, and none of the lidar, radar, ultrasonic crap being used by dinosaur "legacy" auto!

There was a pile up in ohio last week with almost 50. A horrible, thick fog on a major highway near a major city in a rather populated country? That's not that exotic
