"Nuclear is an alternative, but remember you’re not going to have any nuclear cars and nuclear airplanes. Nuclear is not a substitute for oil."

Practically speaking this is true. But you could design a nuclear powered car- of course, the main problem is you don't want people to have easy access to nuclear material- and there is lots other nuclear safety issues. And a nuclear airplane has already been made.
A more practical solution would be to build nuclear reactors with could then make chemical fuel. Of course, if you wanted to do this in a serious way, you devote an entire island to nuclear reactors which created chemical fuel.
Of course, I'm a space nut, so I don't see this as a good solution compared to getting power from Space. But if you insist on keeping to this planet, it would be a solution- decades from now.
