Nit: Most food delivery workers in NYC are on e-bikes or mopeds. There are surely some drivers but it is prohibitively difficult to use a car for food deliveries in nearly all of Manhattan and decent portions of Brooklyn/Queens/the Bronx.
As it is there is public outcry about dangerous and aggressive riding behavior from food delivery workers. It is not strictly a bad idea to tilt the incentive structure so that while you can earn a little extra on tips for completing more deliveries, it's not such a huge part of your earnings that you need to cut corners, ride the wrong way on one-way streets, ride on sidewalks etc. to hyperoptimize your delivery rate.
