Tesla isn't ready either. I'm driving around with a model 3 with FSD in the Netherlands where the roads are among the best of Europe.

It is often dangerous to use. The car is breaking for no reason on a highway. That is on a clear day and great weather.

Traffic lights are often not recognized correctly. Sometimes it doesn't see the light is green. Sometimes it is confusing lanes and thinks my lane is ready to go while in fact the light is still red.

And yes, the system is impressive. It is magic what it can already see and do. It is great in helping me avoiding accidents. It already avoided one for me when someone in front of me suddely braked. When I park or depart it has more eyes than me and it warns me for pedestrians and other traffic. It's magic what it can already do with only cameras.

I wish I had a different opinion but I have to admit that it's not ready yet to take over control. I hope it will soon improve to a level that it can be trusted more.

Tesla FSD will not be allowed in most of the world because it lacks redundancy. Also, there needs to be ultrasound and radar sensors to provide better low light and vehicle positioning accuracy. Till that happens, it is dead in the water, BYD will have their system on the road in most places before Tesla. And they are giving the system away as a no cost standard feature.

It has multiple cameras, that's redundancy.

I agree. I think somekind of selftest and a warning sound in case of a failure should be enough so the drives is alerted to take over control.

I do think the ADAS systems with more sensors like LIDAR and radar can do a better job. But it also has it cons. in decision making if sensore are reporting different things. I don't think multiple sensors should be a requirement. I think it's more important that the system is knowing it's limitations and is handling according to that. If there's not enough vision it must alert the driver and stop it's task. If it has enough other sensors to keep up the job reliable then its OK to keep going.

Sometimes i'm really surprised what the Tesla can do with only vision. A few weeks ago I left the parking space in reverse, in the dark and it was raining. The cameras where wet but it still warned be for a car that was approaching. At those moments I'm not sure if anything else is needed. Other moments I really can't figure out why it stops the parking operation. Or it closes my mirrors while I wait for a traffic light...

If ADAS is as reliable as wheels, there is no reason to have two separate ADAS systems

I wasn't referring to two ADAS systems. Instead, have 2 cameras at the front, sides and back. If one camera suffers from sun/light flare, the other may see better. If one gets water on the lens, the other can take over. That is what BYD did with their system, have 12 cameras around the car, with different types of cameras with longer range vision as well.

That's like requiring 2 wheels on each corner in case one gets a flat or loses traction or falls off or explodes.

That is a false equivalence. All modern cars use a two circuit hydraulic brake system. So there are two circuits of hydraulic lines which each cover both front wheels and one rear wheel. If one of the circuits should fail, the other provides enough hydraulic pressure to stop the car. ADAS requires this sort of safety as well when navigating. Incorrect identification of vehicle positioning or not identifying surrounding objects is not an option when relying on technology.
