Well, at least there'll be multiple toll lanes. Some cities have demand pricing (Atlanta, for one) where there's only one lane and it's separated from the main highway by solid painted lines or barriers. So if you are in the lane behind some slowpoke, you're unable to pass them.

I drove from Austin to Dallas the other weekend -- what a mess I-35 is. And it's been that way for 30+ years. High speed rail could help, if there's good transit connectivity at both ends, and the trains are frequent enough.
