I'm all for delivery robots. The idea of having people in gas guzzling cars taking up huge amounts of city space while polluting, just so you can have a private taxi for your burrito is crazy. The main issue here is them taking up sidewalk infrastructure instead of car infrastructure. Fix that and we've got absolutely no problems. Tiny electric vehicles SHOULD be delivering things. Fixing this infrastructure problem is another great time to fix deliveries in general blocking side lanes, bike lanes, and slowing traffic where it does actually need to flow.

While we're at it, fix all traffic. Switch to a modified Dutch design of three types of roads (highways, distributor roads, and access roads) to further eliminate car interactions with pedestrians, cyclist, and yes probably small bot interactions. They should only be mixing on access roads. Dedicated and separated car lanes, bike lanes, and walking paths, and shared delivery lanes for bots and manned cars on access roads. It'll take time, but a simple plan and slow progress will eventually fix things and cause less havoc like adding cars did to cities that were all horse based.
