This of course assumes 1) that cameras are just as good as eyes (they're not) and 2) that the processing of visual data that the human brain does can be replicated by a machine, which seems highly dubious given that we only partially understand how humans process visual data to make decisions.
Finally, it assumes that the current rate of human-caused crashes is acceptable. Which it isn't. We tolerate crashes because we can't improve people without unrealistic expense. In an automated system, if a bit of additional hardware can significantly reduce crashes it's irrational not to do it.
Also, on a final note...
Why the fuck would you limit yourself to only human senses when you have the capability to add more of any sense you want??
If you have the option to add something that humans don't have, why wouldn't you? As an example, humans don't have gps either, but it's very useful to have in a car
Unfortunately the answer to that is: Elon's cheap and Radar is expensive. Not so expensive that you can't get it in a base model Civic though, which just makes it that much more absurd.
Because a global pandemic broke your sensor supply chain and you still want to sell cars with FSD anyway, so cameras-only it is!
This is directly a result of Elon's edict that Tesla cars don't use lidar. If you aren't aware Elon set that as a requirement at the beginning of Tesla's self driving project because he didn't want to spend the money on lidar for all Tesla cars.
His "first principles" logic is that humans don't use lidar therefore self driving should be able to be accomplished without (expensive) enhanced vision tools. While this statement has some modicum of truth, it's obviously going to trade off safely in situations where vision is compromised. Think fog or sunlight shining in your cameras / eyes or a person running across the street at night wearing all black. There are obvious scenarios where lidar is a massive safety advantage, but Elon made a decision for $$ to not have that. This sounds like a direct and obvious outcome of that edict.
My vacuum robot uses lidar. How expensive could it be??
This kind of idiocy is why people tried to build airplanes with flapping wings. Way too many people thought that the best way to create a plane was to just copy what nature did with birds. Nature showed it was possible, so just copy nature.
To be fair, we achieved flight by copying nature. Once we realized the important part was the shape of a wing more than the flapping.
Humans move with only feet so cars should be limited to using feet. And only 2 of them.
Well building battlemechs does seem like the obvious next step on Elon's progression
You mean promising to build battlemechs, and fucking around for 5 years while grifting his stock valuation sky-high, then coming forward with a cheap robot that can't even walk?
Not only that, specifically doing it to fuck the momentum of another project that would have competed with his entire market but would have been better for pretty much everyone (including those who stayed in the market he was targeting).
Regarding point number 2, I have no doubt we'll be able to develop systems that process visual/video data as well as or better than people. I just know we aren't there yet, and Tesla certainly isn't.
I like to come at the argument from the other direction though; humans drive with eyesight because that's all we have. If I could be equipped with sonar or radar or lidar, of fucking course I'd use it, wouldn't you?
If the camera system + software results in being 1% safer than a human, and a given human can't afford the lidar version, society is still better off with the human using the camera-based FSD than driving manually. Elon being a piece of shit doesn't detract from this fact.
But, yes, a lot of "ifs" in there, and obviously he did this to cut costs or supply chain or blahblah
Lidar or other tech will be more relevant once we've raised the floor (everyone getting the additional safety over manual driving) and other FSDs become more mainstream (competition)
The thing is that you don't need FSD to do that. Having a really good AEB system massively improves safety, far more than a convenience feature like FSD does, but they fucked that up by taking the radar out so now it performs far worse at night, hence running over pedestrians and other VRUs far more often.
But you can't grift billions out of investors by having a really good safety feature, so you hack together a system from hardware only ever originally only meant for adaptive cruise and lane keeping, and tech bros can show off on YouTube and hopefully not run over a cyclist, all to keep that grift rolling
