How many hours can a car run continuously?

[DelMila]

A car can run continuously for four hours, as regulations prohibit drivers from driving while fatigued. The details are as follows: 1. Driving on the highway: If the speed remains consistently uniform, the car can easily cover ten thousand kilometers without any issues, provided there is sufficient gasoline. 2. A car can continuously drive a distance of no less than ten thousand kilometers: All cars undergo numerous tests during production. Before manufacturing, cars are subjected to durability tests exceeding forty thousand kilometers and continuous operation tests of one thousand hours, ensuring they can be used in the market without major issues. In addition to these tests, manufacturers also conduct separate tests on the car's chassis, tires, etc., typically lasting over a month and a half. Therefore, cars undergo continuous operation tests exceeding forty thousand kilometers and even four hundred thousand kilometers on the platform.
