Are we talking different levels as in Level 3 vs 4, or different levels within each level? I'm not sure about the latter, but this regulation only came into effect at the start of 2021 so I wouldn't be surprised if more don't yet exist.
If we think the bar is being set low, following is a link the standard
Do we think Autopilot could currently satisfy paragraphs 5-9? If so, I can't imagine why Tesla wouldn't be pushing for this and pushing to sell a Level 3 certified system if only as a branch of the current Level 2.
I think we need to be careful not to confuse capability with what the manufacturers are allowing. Tesla allows the vehicles to do all kinds of stuff while calling the system Level 2 and making the driver responsible for anything bad that might happen. You can be sure the Mercedes system is capable of attempting far more, but they (and the other brands generally) are much more conservative in what they'll allow in the vehicles -- these are fundamentally different approaches.
For a consumer who I think has no bias and would just like a vehicle that will add value by driving itself safely under conditions that I understand while allowing me to focus on other stuff, I don't really care if my vehicle will attempt more complex maneuvers if I'm ultimately responsible for them and need to always be paying attention and in control. If I need to do that, may as well drive the vehicle myself on regular cruise control.
I drive somewhere around 3,000miles a month right now and 95% of it is straight lines and slight curves on highways. I'd pay a good chunk of money for a system that could do that 95% of the driving while I focus on anything else, but I wouldn't pay a red cent for a system with the same or better capabilities where I still need to apply wheel torque or have my eyeballs constantly pointed out the windshield.
Taking responsibility for the driving task in a consumer vehicle held to international standards, even under limited conditions like these, is a massive step and something that Tesla has not yet attempted.
