How can self driving cars help the environment?
Most gas is burned when driving at high speeds, braking, and re-accelerating excessively. Self-driving vehicles cut these factors out of their driving style, meaning less gas is burned, or battery power consumed, resulting in less air pollution. Driverless cars also mean fewer cars per household.2 avr. 2021
How cars affect human health?
