The thing is humans are horrible drivers, costing a huge toll in lives and property every year.
True
We may already be at the point where we need to deal with the ethics of inadequate self-driving causing too many accidents vs human causing more.
Are you talking about waymo vs human driver? It’s currently (and maybe never) economical to roll that out globally. That would cost trillions and probably wouldn’t even be feasible everywhere.
Teslas aren’t autonomous but just mere driving assistants so you can’t compare them. Otherwise you’d also have to include the Mercedeses (which btw have the first commercial Level 3 car), BMWs, BYDs, …
but is it ethical to block Immature technology if it does overall save lives?
It would be very unethical to allow companies to profit from dangerous and unsafe technology that kills people.
This stuff is highly regulated https://en.m.wikipedia.org/wiki/Regulation_of_self-driving_cars
Mercedes has the first autonomous car (L3) you can buy, which you can only activate at low speeds on certain roads in Germany. It’s only possible because of Lidar sensors and when activated you are legally allowed to look at your phone as long as you can take over in 10 or so seconds.
You aren’t allowed to do this in a Tesla, since the government doesn’t categorize Teslas as autonomous vehicles which requires L3+.
No car manufacturer can sell real autonomous vehicles without government approval. Tesla FSD is just Marketing bs. Others are far ahead in terms of autonomous driving tech.
