I've noticed lately that a lot of the DoorDash/Grubhub food delivery drivers are on mopeds. Instead of, you know, automobiles. It makes sense: in a highly competitive game of being stuck in San Francisco traffic, the moped (and its motorcycle cousin) is hugely advantageous. The ability to weave in and out between stuck cars is crucial in ensuring that KFC order gets to the customer with reasonable temperature left over. No one likes cold fried chicken - a congealed mass of molasses.
There's advantage in parking, too. As in, there isn't a need to park a moped. Not that delivery drivers in cars obey the parking rules anyways. The speed demand means they double-park, and simply play the lottery of "hope you don't run into a meter maid." (Or an angry driver stuck behind.) I can confirm this to be the case, because my brother for a time did food delivery as a somewhat full-time job. (Surely he does not miss hustling in traffic all day for a measly $100 payout.) With a moped or motorcycle, the riders park them on the sidewalk right outside the restaurant.
What makes the proliferation of moped-as-delivery vehicles interesting is that in Asia, this has been the modus operandi for a very long time. You go to any major city in Asia, and mopeds are absolutely everywhere, ferrying all sorts of things. It's driven by necessity, of course: it's far cheaper to buy and own a two-wheeler compared to a whole car. Americans don't realize how, relatively to the rest of the world, car prices here are cheap and attainable. (Gas prices, too, in the non-Saudi Arabian category.)
Will mopeds become as the gig commerce vehicle of choice here in San Francisco - a la Asian cities? I think it depends how inflation-proof the gig economy is. Buying food - much less having someone deliver it to you - has become prohibitively expensive. If the economy contracts due to high interest rates, surely people will be way less inclined to order on DoorDash.
This is the sound of settling.
