Once the libs start thinking about this, they may back away from it or alter it. If I understand the current proposal correctly, Big, evil, diesel or gasoline swilling SUV’s would pay the same as a Prius........can’t have that, now can we?
If they continue down this path, the price charged per mile will be based on vehicle weight....mark my words.
And by time of day, and by which road you choose, and by number of occupants, and on and on. They will have a detailed record of when and where you drive your car -- incredible and unnecessary invasion of privacy.
