My view is that free charging of any kind is a nice perk, and I personally feel fortunate to have this perk in any form, even a limited one. I don’t understand the sense of entitlement that leads a person to be mad about getting something for free, even if it does come with limitations.
Practically speaking, once the 30 free minutes expire, why not just pay for whatever extra you need and be thankful for the free electrons? VW didn’t have to offer any free charging at all, btw, but I can only imagine the stink that would’ve caused. Sigh…
