A co-worker has a Tesla and lives near me in southern IL which is about 37 miles from the St Charles MO SC. Here's how he helped to justify and afford his Tesla MS 85.
His daily commute is almost the same as mine 22 miles R/T about 150 miles a week.
He would drive over to the SC early Sunday morning and "fill up" for free, during his hour he read the paper, checked E-mail and sipped coffee at a nearby coffee shop. He would charge to the recommended 90% SOC and then drive home and plug in to his home Level II charger and top it off. Then he could drive all week on that charge. He claims he has never used more than the 200 miles or so of charge.
So he was only charging at home consumed about 13 to 14 kWh per week, and at 11.5 cents per kWh it was costing him about $1.50 a week to operate his CPO Tesla. He claims he has never gotten any nasty e-mails from Tesla about misuse of a SuperCharger.
I asked him if the new "pay to charge" policy would change his mind and he said "sure" it'll be cheaper to charge at home. But for now he's being grandfathered in the FREE FOR LIFE and doesn't plan on buying a new Tesla until his CPO warranty is about to end.
So this is a brilliant move by Tesla to ensure their SC network is available to support long distance travel. People will be people when it comes to getting something for FREE, sad to say.
