It would be truly interesting to see what a fossil fuel company can/will do in an all BEV future. The thinking around creating EV "gas" stations is wrong. The only way it would work is if charging speeds get down to single digit minutes or even the low teens.
I think a more probable futures is that "gas" stations disappear altogether and everyone will use destination chargers. Maybe the future is (most) all parking lots have a plethora of charging spots spread all over and people just plug in while getting groceries, or going to the movies, or buying shoes.
Sure, Tesla had to create Supercharging locations because they were the first. However, I think it would be much more interesting for companies like Shell to pair up with companies and put chargers in every parking spot. I could imagine plugging in at Chick-fil-A while I get lunch, or Lowe's while I purchase some LED light bulbs. This would actually work pretty well for those folks that don't have charging at home or at work. Just drive around and charge a little bit at each stop you make.
