Honestly I think there's a great role something like Uber could fill, simply as a nationalized, not-for-profit tax funded arrangement that businesses could opt into, maybe even a branch of the post office. Ensure delivery people get good benefits and pay for doing a needed job, and the service brings those people, restaurants and stores, and consumers together. We could make things more convenient for people, provide businesses with more opportunities to sell their products, while providing a lot of jobs to people who need them, and also cutting down on the number of vehicles going around at any given moment.

The main drawbacks to these services are the outrageous fees they charge to make money, and that there's more than one so drivers and businesses have to manage an array of phones or tablets. This would address both of those things.
