I hate to sound picky, but as the Supercharger network continues to expand, I've noticed that little attention appears to be given relative to the quality of food available at many locations, especially for vegetarians. The reality is that on long distance trips, you try to time eating with SC stops rather than making separate stops to eat. The problem is that many stops just don't offer great eating options.
For example, the new Rolla, MO SC is located at the parking lot of a Bandana's BBQ restaurant, with no other options nearby. I've also been to Superchargers in Binghamton, NY and South Hill, VA, which are similar situations. Some SC's over extremely good eating options, such as the one in Edison, NJ that has a Seasons 52 and a Macaroni Grill close by, or Woodbridge, VA that has a wide range of options.
I'm currently planning my holiday travel, as as a vegetarian, the I-70 seems to be an endless chain of fast food, steakhouses, and BBQ joints. Considering how you're likely to spend 40 mins at an SC stop, I'd love it if the onboard app would provide some drill-down detail as to food options at SC stops, like the website does.
