How does one get past the registration/paywall?
How does one get past the registration/paywall?
The article misses an important point. It’s not only a problem of technology, it’s also a problem of risk acceptance. While we accept to be killed by our own mistakes at the wheel, society (we) will not accept that a machine makes the same, even if the failure rate is on average /better/. This is the fundamental issue Elon Musk has. The driverless bar for safety is way higher than very clever driver assistance or eve…
>While we accept to be killed by our own mistakes at the wheel, society (we) will not accept that a machine makes the same Ideally we should not be accepting either. It is outrageous how many people we allow to be killed regularly for slightly more comfortable transport.
The most pertinent point here being that although collecting lots of self driving car data is easy, the tail and unexpected events that you care about are surprisingly rare. And many of these events can also be entirely new (never seen before). Current AI SOTA techniques simply require too much data and cannot reason well enough to solve this. Leaving Musk aside, amongst those who are serious about self driving cars,…
I agree that ditching Lidar by Musk is the wrong move. From what I have read most if not all the self driving accidents that Tesla have been involved in could have been avoided if a Lidar type sensor was involoved. With tech available trying to use the same limits as human vision is stupid.

Oh wow, it can stay in a lane and match speed! So can every car manufacturer. They’ve got a level 2+ system and cars won’t be safer until level 4.

If they had someone working on using the tech to ID mushrooms growing along the road then they’d probably come away with some new techniques to make the cars safer. Trying to make a self-driving car algorithm by only thinking about driving-related things seems like it will just lead to overfitting.
And in fact any car that doesn’t have enough cognitive surplus to identify mushrooms while driving in normal conditions may just not be safe to drive period.

The goal is not to achieve perfection, just demonstrably more safe than an average driver.
I'm curious how we will evaluate average driver. Clearly, including drunk driving accidents in the mix is not a helpful metric for safety-conscious drivers.
Maybe we should focus on finding a way to ... clone our brain inside of mechanical box. I know plenty of ethical considerations there, but a human with all the life skills of a human would be a perfect AI and not need the normal learning that focus ML brings w/ it. Imagine if they just clone a driving instructor's brain, and placed copies of that inside the cars...

I agree with Musk and George Hotz that lidar is never going to get there. That's because in Michigan the terrain that lidar has mastered changes drastically every time it snows. For those of us in snowy climates limiting us to self-driving to seven months a year isn't going to cut it.
