What are the advantages and disadvantages of driverless cars?

Here are the advantages and disadvantages of driverless cars: 1, advantages: (1) Reduce greenhouse gas emissions: driverless cars can find the best acceleration, braking and deceleration modes through their control systems, effectively improve fuel utilization, reduce greenhouse gas and harmful tail gas emissions, and be more environmentally friendly and energy-saving. (2) Relieve traffic pressure: reduce the probability of traffic congestion caused by accidents. Smart cars can monitor real-time road conditions and plan optimal routes through satellite navigation. 2. Disadvantages: (1) Safety cannot be completely guaranteed: totally relying on the automatic driving system will increase the accident rate. (2) Too much dependence on satellites and networks: Unmanned driving technology relies heavily on satellite navigation technology. Once the signal is disturbed or even interrupted, the driverless car can't receive the information of Google Maps on the way.
