This statement is not true. According to California Air Resources Board – Cars and Light-Trucks Are Going Zero (FAQ), and CalMatters news article on California’s electric vehicle rule.California’s rule says all new cars, trucks, and SUVs sold in the state must be zero-emission by 2035, not 2030. The plan slowly increases the share of electric cars each year until it reaches 100% in 2035. People will still be able to buy and sell used gas-powered cars after that date. So, there is no full ban by 2030. It was originally supposed to be 2030 acouple years ago but that has changed since.
