1. For at least one publicly available model still being produced

2. Can be publicly used at this level

3. In the USA or Europe

4. Evalution is not well-defined but I will use the best combination of Tesla's claims + US/other country national or state administrators judgments

5. If the US, the area it is approved for is evaluated based on the entire state. (i.e. if one road is approved for SAE 4 but the rest of the state is SAE 3, then that counts as SAE 3)

6. But primarily will use actual accepted user behavior (i.e. if you can legally drive in that region at that SAE)
