不对。美国的标准是62英里/100km/h。 好像是特斯拉最高200mph,但Audi Q5设在52mph，不知道为啥

The standards require vehicles to stop and avoid hitting a vehicle in front of them at speeds up to 62 miles per hour (100 kilometers per hour). Also they must apply the brakes automatically at up to 90 mph (145 kph) if a collision with vehicle ahead is imminent.
