It's like walking blindfolded into a restaurant and putting your tip in the hostesses hand before you even see any of the staff, or have any indication of service.
That's a pretty silly system.
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.
Things a dasher is responsible for:
1. The correctness of the order. Yes, it's fair to hold them responsible for this, because they have the order and they are at the restaurant. If the order is wrong, they can easily correct it then. If it's wrong at my house, now what? Probably I'm unhappy, even after Door Dash offers me credits
2. Keeping the food in good shape. That includes heat (some dashers use a heat bag), but it also includes keeping soup, chili cheese fries, and other things upright. (All things some dashers have screwed up for me.)
3. Paying attention to notes. I eat my Taco Bell with diablo sauce. Did he include the sauce I asked for in the notes? (Bonus points for including things like napkins and sporks without being asked.)
4. Polite behavior. Most are polite, but some practically throw the food at you and run away.
