With all due respect it certainly is, at least in America. Otherwise we'd be like say.. Germany, where you have to 'report' to the local Police Department when you move to a new city. As to the roads and how we get "there" - we're paying for the roads in more ways than just the gas tax.
Anyway this 'pay by the mile' bull baloney is nothing more than some socialistic Urban Planner's wet-dream and is nothing more than an electronic version of "your papers please".
After all they really don't want us to travel anyway. "They" want us all to live in one big city using "public transportation" and see personal travel (commuting) and "suburban sprawl" as one big evil that must be contained - "for the common good".
Easy Solution right here.
State of Texas should tax aviation fuel. Texas is the only State I know of who exempts aviation fuel.
