The difference between "self-driving" and "private car" in English can be a bit nuanced:
"Self-driving" typically refers to the act of driving a vehicle oneself, without any assistance from others. It emphasizes the personal experience of operating the vehicle.
"Private car" refers to a car that is owned by an individual or a private entity, as opposed to a vehicle owned by a business or used for public transportation.
As for when each is suitable:
Self-driving: This is suitable when you have the legal driving age, a valid driver's license, and you are comfortable operating a vehicle. It's ideal for personal transportation, daily commutes, road trips, or any situation where you need to navigate from one place to another.
Private car: This is suitable when you have the financial means to purchase or lease a vehicle, and you require a vehicle for personal use. A private car is ideal for those who need a vehicle for regular transportation, whether for work, family, or personal reasons, and want the convenience and control of having their own vehicle.
In summary, "self-driving" is the act of driving, while "private car" refers to the vehicle itself. You would choose to self-drive when you are operating a private car for personal transportation.
