" The estimated annual payment is about $75,000
Straight from the article., I still don't see the value at 1/10th of it, if you are talking 12 vehicles per day at a couple dollars a piece, savings. You don't save a thing, and I doubt that charging would be at full capacity, besides which, you are giving it away.
Illogical to assume a profit here, there will be no cost benefit to the dealer, and no cost benefit to SLMU, that I can see, without a whole lot more that hasn't been disclosed, I'm waiting to see if it is there, or not.
