Well, my actual thought was more that adjusting tips based on perceived delivery driver performance is somewhat unfair based on all the things beyond the driver's control. (I'm not sure if the downvotes I got are from people who think I was arguing "never tip drivers" and are mad because they think I'm a jerk, or people who realized I was more arguing "don't undertip drivers" and are mad because they think I'm saying undertippers are jerks, and fair, I am.)

Anyway, yes, actually: I think there's a good argument to be made for a higher wage for delivery drivers -- and all waitstaff -- that makes their earnings less dependent on tips. If people want to tip for exceptional service, that's fine, but there are a surprising number of people who treat tips today as if they're only for exceptional service, will cut tips in half or even to zero for things beyond the server's control (e.g., the restaurant will not accept your clearly expired coupon), etc.
