Turk, that's a great question.

Where did Wilf go?

I like...

Can't wait until you start driving!

I think that's a tough one because I think of "can't wait" as a somewhat active and positive verb in and of itself.

If the question were:

Can't get it up, also!
Can't get it up, either!

Definitely either. But when I can't wait, I'm actively can't waiting.

I think either way (also way?) works.
