When driving on the road, one needs not only a good sense of abiding by the law, but also a special rational calculation  In the congested traffic, as long as there is a jam, your car must give way to it; you drive straight on the road normally, and there is a car that suddenly comes across near you without a direction light to bump into you
rational calculation is actually timid, always feeling that everything can be avoided, but some things are difficult to avoid
 It turns out that it wants to change lanes, and then you have to give way to it
