There's no such thing as "free" parking, and the term "freeway" has nothing to do with tolls. "Freeway" is simply a reference to a limited-access roadway with no traffic control devices (traffic signals or stop signs) that interrupt the flow of traffic.
I like Alberta, but have never had to pay to park while there, though I'm sure that those who demand to pay to park are accommodated by some sharp people fulfilling that need.
Freeway comes from California where the roads are free from additional fees, unlike say, the Indiana Toll Road (recently on the auction block to some Spanish company).
I've driven on both, I have no trouble telling the difference.
I'd still submit that those places where they have free parking are being true to the American way. Democrats want people to pay to park so they can restrict their mobility and create dependence. Free Parking is independence. No, I'm not kidding.
