A 2019 Tesla Model 3 Standard Range Plus has covered 380,000 miles (610,000 km) on its original NCA battery pack, a real-world data point on Tesla longevity rather than a manufacturer test. The pack now displays 158 miles of range against the original 240-mile EPA figure — a 34.2% capacity loss — but the car still meets its dynamic specs and remains usable as a daily driver.

SAE J3016 is the international standard that defines six levels of driving automation — from Level 0 (none) to Level 5 (full). Every Tesla sold today, including vehicles running FSD (Supervised), is Level 2. This guide explains what each level means, where the legal lines are in Europe and the US, and what changes in practice for you as a driver.
