It only takes a free 20 minute charge to drive for 3 hours. Most people have to take a piss stop ever 2 hours. Who the hell drives that far anyway? I have never driven across the country in my life. But hey if it can now be done for free more people might try it.
"95% of trips are less than 30 miles. More astonishingly, around 98 percent of all single-trip journeys were under 50 miles in length, with trips over 70 miles in length accounting for just one percent of all single-trip journeys." GM determined 80% drive less than 40 total miles a day. It would take all week to drain the Tesla battery at that rate so 1 weekly 20 minute stop at a free recharge station will save you $40k in 200k miles.
And what if there is four other Teslas ahead of you? That would be an eighty minute wait providing people move their asses and you still have to wait another twenty to recharge your car. I'm sure these charging stations won't have an infinite numbers of access points. Are you willing to throw the dice every time you reach a charging station (every three hours)? I'm not. My time is far more important to me, than some Feel good green technology, but I'll be sure to wave as I pass you by.
There will be more available recharge ports than gas stations had available pumps. It is cheaper to build these charging stations than a multi million dollar gas station. These charging stations don't have to deal with EPA underground tank, fuel storage, fire & spill regulations. They also don't need cash registers or attendants.
If they don't have attendants, the stations will be stolen. Like the bikes are stolen from bike share stations.
This is going to be one of those things that looks real good on paper. Not so much otherwise.
