I guess that's nice if you live in San Francisco. Same day delivery doesn't exactly seem that challenging if you only deliver to a 30 minute radius.
Unless you had self-driving cars with real time map data.
Sounds like you may be doing it wrong. I lived there for 4 years. Public transit, biking options etc were all decent.
You talking about on the 101 during rush hour? I bet their algos would easily avoid that.
