Yeh things will change... you sorta already see stuff like this in Asia where drivers are common... people have vans with offices in the back and work while their driver takes them to places.
Drivers in Asia are, to my understanding, very common... Idk about the office/van. I just know one guy in South Korea that has that setup and he is rich. He says other people have it but not sure how common it is.
But "executive" back seats are very common on luxury brand vehicles in China.
