That's only if those cars are doing things that wouldn't otherwise be done.
If you drive for grub hub and deliver to me instead of me going to get my own burgers, the amount of driving hasn't changed for the vehicle fleet as a whole. In fact if a grub hub driver drops off for 3 customers the total driving is in fact less because it involved 1 trip to the restaurant rather than 3 roundtrips. I'm not saying you are wrong about your stock pick. I'm saying I believe your reasoning is wrong.
