Self-driving in general has been overhyped by grifter tech bros like Elon and really shows the current limits of ML. Today, ML models are basically fuzzy, probabilistic functions that map inputs to outputs and are not capable of actual reasoning. There is a long tail of scenarios where a self-driving car will not generalize properly (i.e., will kill people). Throwing increasingly more data and compute at it won’t suddenly make it capable of reasoning like a human. Like other ML use cases, self-driving is a cool concept that can be put to good use under the right conditions, and can even operate mostly without human supervision. However, anyone claiming it’s safe to let today’s “self-driving” cars shuttle humans around at high speeds with no additional safeguards in place either has an unrealistic understanding of the tech or is a sociopath.

IMHO, this was really a video about camera-only automatic emergency braking, not autonomous driving.

Lots of cars have AEB now since a lot of regulators are requiring it, but most use a combination of cameras and ultrasonic sonic. The top-of-the-line systems have LiDAR, cameras, and ultrasonic.

Tesla’s sensors lack redundancy. If the cameras are obstructed or can’t distinguish shapes, the vehicle can’t fall back to another system.

Coming here because I saw how downvoted this post was on Reddit lol. I love that it's triggering the Elon fanboys.

Maybe it was downvoted because of Mormon weirdo Mark Rober and not the content itself?

[–] Jollyllama@lemmy.world 17 points 1 day ago

Based on comments it's the Tesla stans.

Is he a weirdo for being Mormon, or something else?

Seems like most of the downvotes are in the Telsa communities. The other communities upvoted it heavily.

Thank god it doesn’t have LIDAR sensors, much cheaper to repair the front this way

Tap for spoiler/s

Ahah Tesla is like a 2000s knock-off of good existing technology

Props to Benn Jordan for doing this a year ago on a slightly lower budget.

Bonus deep dive about using LiDAR to map out space mountain

I never trust self driving/autonomous car no matter how advance their tech are

[–] simplejack@lemmy.world 5 points 1 day ago

Having clocked in a lot of hours in San Francisco cabs, Ubers, Lyfts, and Waymos, IMHO, the Waymos are the least terrifying - by far.

My opinion might change if they’re ever allowed to travel at high speeds on a highway, but in a congested city where you can rarely get above 35mph, they feel really good.

No aggressive or distracted driving, no tipping, no stinky ass air freshers, and generally no double parking to pick people up.

I’m a convert.

Insane that the telsa drives into spaces its unsure of. So dangerous

[–] danc4498@lemmy.world 7 points 1 day ago

Sure, but their sensors will detect if you aren’t paying enough attention and report back to Tesla headquarters to get the lawyers ready before you can even get out of your car.

That's the thing that got me. I would have issues spotting that child through the fog as well, but I wouldn't have sped through it.
