Wasnt the free charging for Tesla only for certain models and for a certain number of years? But if you didnt see, earlier this year, Tesla increased it's supercharging prices in NY and CA (and maybe a few other places), and the internet calculating the equivalent gas price (based on miles per charge and cost, etc) it was more expensive to "refill" than gasoline (of course dependent on the gas price of those same NY/CA areas etc).
Which caused an uproar and forced Tesla to lower the prices to appease.
