I have visited Tibet many times, always by car.

Personally, when entering Tibet, you should not go with a group, you must help yourself.

In fact, there is nothing special to pay attention to, but you need to have a calm mind, treat yourself as an elderly person, slow down your thinking pace, and slow down your movement pace even more! After all, the oxygen content is very low.

Then, beware of colds! For people living in the plains, once they reach the plateau, a small cold may be fatal!

The last time I went to Tibet, I started from Beijing, entered Tibet via the Sichuan-Tibet line, and left Tibet via the Qinghai-Tibet line. It took three people, one car, and lasted 22 days. I needed tolls, gasoline, meals, accommodation, and tickets. ***12,000 yuan, average 4,000 yuan/person, your personal expense is film.
