I saw that article and saw that most of the negative comments were to the effect that the taxpayers would be paying for the electricity, oblivious to the fact that in order to charge you'd have to be paying for parking -- effectively they're offering a discount to EV's and it may drive a little more business to those garages while also promoting EV's. To me it would just be an expensive way to charge my Enertia (those garage rates are ridiculous).
I wish they'd give EV's an exemption to the parking meters (for now). Heck for my personal needs it would be sufficient if they wouldn't ticket EV bikes parked between car spots (with expired meter).
