Tips

culture
Reads as English 'L-three'. SAE autonomous-driving levels (L0–L5) are heavily marketed in Chinese EV ads. L2 = driver-assist (lane keep + ACC). L3 = car drives itself in defined conditions (driver still on standby). L4/L5 are higher tiers. China issued its first L3 trial licenses in 2024.
