Food delivery drivers in our area are from what I've noticed mostly using scooters. Because in traffic they can get one where in half the time; not to mention costing less to own and operate then even a Prius.
That said when my partner and I see a Prius it's synonymous with Uber i.e. that Uber just cut me up.
I have noticed that the MG5 is making in roads though as the electric taxi of choice.
