It is generally more appropriate for several people to carpool on the Sichuan-Tibet line.

1. If there is a car with a large displacement, it is more appropriate to have 5 people and 4 people in a carpool. To ensure the comfort of the rear passengers during long-distance driving. If the displacement of the car is too small, take two or three people to ensure that you can have the power to climb the hill when driving on the uphill section at high altitude.

2. If the vehicle has a large displacement and carries 7 people, it is more appropriate to carry 5 to 6 people in a carpool to ensure that there is enough space for the salute.
