How tiring will it be for a driver to travel by car?

As someone who has driven nearly 50,000 to 60,000 kilometers abroad, I think: 1. The number of kilometers to transfer points by self-driving (whether domestic or foreign) cannot be too many. I usually control it within 300 kilometers. Countries such as Serbia, Montenegro and Bosnia and Herzegovina must even be controlled within 200 kilometers. 2. You must not copy the tour group's route and time schedule. Each of their attractions has a time limit and is a check-in type. Self-driving tours are a slow-paced resort-style tour with deep freedom, not to mention that they have full-time drivers and tour guides. Tourists can sleep in the car and check into the hotel when they arrive. For self-driving tours, tourists have to continue driving and find hotels or B&Bs. 3. For self-driving, you should stay in a certain city for three to five days and visit the surrounding small towns. Tour groups will never go there, and the beautiful scenery is often found in those places. 4. If time permits, try to avoid highways. Not only will you save money, but the key is to avoid highways so you can 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 rights of way, otherwise, accidents will be too easy.
