Level 4 exists in the form of Waymo, who operate on roads with shoddy regulations (random US municipalities), so probably not proper Level 4. Also exists in Japan, which does have proper regulation but from what I know it’s still a pilot.
Level 3, conditional automation, is becoming quite standard in the upper market segment. Things like traffic jam assist: You can actually take your hands off the wheel and eyes off the road, when traffic clears up the car will alert the driver to take over again, or, that failing, pull over on the shoulder and presumably call emergency services.
Tesla’s stuff is Level 2, needing constant monitoring by the driver.
