Jerusalem has very little snow and rain and most of those roads were clearly marked. Mobileye may have very little capability in inclement weather. Autosteer does a decent job of at least holding lanes in bad storms, as long as all the sensors and cameras aren't blocked.
The other thing you have to keep in mind - if Tesla can do 80% of what the competitors can do for half or less of the cost, they are ahead. They are actively monetizing FSD, even if it's only level 2 and stays that way for a while (hopefully city NoA this year). People are paying real money for FSD, even if some are understandably getting impatient. It's likely a profit center for Tesla already, or will be soon as they recognize deferred revenue (forget about robotaxis). These CES demos are to try and get OEM's interested in dumping in millions to make a real production ready solution. Prototype vehicles can cost hundreds of thousands of dollars each; they are money pits.
I'm sure the Mobileye route was carefully chosen and most of the bugs worked out. It's a more complicated version of Tesla's FSD demo,that's all.
Tesla's betting that they can stick with the limited camera and sensor suite and progressively put more and more computing power into it, retrofitting the FSD computer multiple times. It's a reasonable gamble. It's way easier to swap one control module multiple times and reuse the same sensor suite. For other OEM's the customers will have to opt into the sensor suite. So they have millions of cars on the road that are definitely dead end for FSD capability. You can't take a million Rav4's in the market and install 8 cameras on them (I mean you could, but seems infeasible due to the places cameras are mounted). But you might be able to retrofit a million Model 3's to a new HW4 computer, when they were specifically designed to be upgradeable from the beginning. It's no more work than a major recall which often has millions of affected vehicles.
Teslas current sensor suite might work out with progressively more powerful FSD computers--they are taking a gamble, and it will be fascinating to see if they pull it off.
