I feel like I would use it voluntarily if it put the sponsors in the “add a destination” menu. I tend to use Google maps for longer trips, and I try to add any stops on the way to my route so I don’t miss them - if I hit “add destination” and it offered, for example, Citgo stations, 7-11s, and Dunkin Donuts on my route, then I would probably get gas and snacks at sponsored locations almost every time.

As it is, though… Well, just having a Dunks on the way to the laundromat doesn’t make me want to stop in and buy a coffee. Driving by ten of them “randomly” on my way to another state isn’t going to make me any more likely to stop at one.
