Wash. considers annual flat fee for electric cars

This isn't a new idea, they've been batting it around ever since the Prius sales started ramping up when gas hit $4+ a few years ago. It's either this or private toll roads everywhere...

I agree - the either/or options have too many drawbacks.

dp - I really like your #1 option, except for the GPS tracking part.
#2 will serve to merely punish the late adopters of electric only vehicles
#3 I'm assuming would be modified based on electric vs gas? But then would a better gas mileage car be charged less than a lower gas mileage SUV?
#4 is like #1 - would it simply be the DMV folks walking out and checking the mileage for themselves, or would the gov't try to implement a "certification" system, like emissions tests (you have to get your car mileage certified, and pay a fee to do so, before you could re-register?). That latter part sucks.
#4 (2nd) then people who drive gas powered cars are being punished, as are people who don't drive at all.
#5 in lieu of charging more for registration? Registration brings in a more steady flow of cash, which is needed for maintenance, than does car sales. This probably wouldn't generate enough revenue.

I like the thinking though!
