Tesla could be the next big thing in roadside rest stops.

That is, in an effort to expand and improve its Supercharger network, Tesla is mulling the restaurant and convenience store business. Or, more likely, it could end up in one or more partnerships with companies that are already in these businesses.

The notion of all this came up when Tesla CTO JB Straubel raised the possibility at FSTEC, a food-service technology conference and trade show, last week.

As the network of Supercharger fast chargers grows, so do the opportunities to refuel the people waiting for their cars

“People are coming and spending 20 to 30 minutes at these stops,” Straubel explained. “They want to eat, they want to have a cup of coffee, they want to use the bathroom.”

Straubel said that at this point Tesla doesn’t want to manage its own network of restaurants and convenience stores, thus it could pursue partnerships with companies. Outfits like existing gas stations, truck stops, and convenience stores are all opportunities for a Supercharger partnership.

Tesla already has a partnership with the Ruby Tuesday restaurant chain. It was announced in the summer of last year, with chain revealing plans to add superchargers at some of its more than 700 restaurants. Tesla also has a partnership with gas and convenience chain Sheetz, with the chargers beginning to appear now.
