That's interesting idea, but it'd be very challenging to scale. Most rural towns have far fewer restaurants compared to cities, and of those restaurants, a significant portion serve food that's not sufficiently different/better from gas station food to justify paying a premium for it. It doesn't seem out of the realm of possibility to create an app that lets truckers queue up an order ahead of time - but even if you did, you're ultimately catering to a dying market/industry that'll inevitably disappear sooner rather than later.
