How tired will a driver be when he is in road trip?

As a person who has driven nearly 50,000 to 60,000 kilometers abroad, I think: 1, the number of kilometers driven by car (whether at home or abroad) should not be much. I generally control it within 300 kilometers, and some countries such as Serbia, Montenegro and Bosnia and Herzegovina even control it within 200 kilometers. 2. Never copy the itinerary and schedule of the tour group. Each of their scenic spots is time-limited, which belongs to the nature of punching in, while self-driving is a holiday-style tour, with free depth and slow pace. What's more, they have full-time drivers and tour guides. Tourists sleep when they get on the bus and stay in hotels when they arrive. In go on road trip, tourists have to keep driving and look for hotels or host families. 3, self-driving, with a city as the center, stay for three to five days, and take a walk in the surrounding small towns, which is absolutely not for tour groups, and beautiful scenery is often in those places. 4. If time permits, try to avoid expressway, which will not only save money, but also avoid expressway to enjoy the beautiful scenery and stop to take beautiful pictures. 5, self-driving, especially foreign self-driving, must have excellent driving skills, especially a deep understanding of the concept of foreign road rights, otherwise, it is too easy to have an accident.
