The purposes and significances of a self-driving travel can be expressed in English as follows: "To enjoy the freedom of driving and to explore the unknown."
Here's a more detailed explanation:
1. Enjoy the Freedom of Driving: Self-driving travel allows individuals to have complete control over their journey. This sense of freedom can be liberating, as it enables travelers to choose their routes, stop at places they find interesting, and make spontaneous decisions without the constraints of a scheduled tour or public transportation.
2. Explore the Unknown: Self-driving tours can take travelers to places that are not widely known or easily accessible by other means. This can lead to unique experiences and discoveries, fostering a sense of adventure and a deeper connection with the destinations visited. Exploring the unknown can also provide a richer understanding of different cultures, landscapes, and natural wonders.
