What do you think public transportation will be like in 30 years?

In 30 years, I will be over 80 or you can say I will be near 90. So it's difficult to think about it.
For these 30 years public transportation has changed a lot. Many people have cars, especially in provincial area it's difficult to live easily without cars. However it's only a matter of time before many  senior people can't drive by themselves.
So I think auto driving electric car for one or two people (does it make sense?) will be popular in 30 years. If it comes true, I will be able to go out by myself without drivers.
What do you think of it?
