It's a decentralised solution joining would-be serial sex offenders with potential victims. (Only partially joking)

The externalities of the existing taxi licensing systems are not perfect, but removing even the quasi-accountability of a corporate entity like Uber seems worse.

Exactly this. One serial killer in comments above isn't happy about public feed and wait it to be more secure (only partially joking).

Good news is you have source code now and author who is happy to accept improvements. Please improve accountability and safety - you can't do it with entities like Uber probably.

Uh, are you seriously equating someone commenting on the lack of privacy with the them being a serial killer?

It's not clear, if this is a replacement Uber Client, or a whole new decentralised infrastructure for being an unlicenced taxi. Looks like it might be the latter.

Ride-sharing model but better in their view

Is it based on GPS locations?

It is a technical solution that lacks a network effect or regulatory OR people component

It also seems to be lacking the technical component as I didn't seem to find any dispatching logic (e.g. geospatial awareness).

Isn't that what Uber is? The people component only exists when they're trying to manipulate customers into thinking they care about anyone. If you actually try and get support over being harassed by drivers for example, you get to see the real Uber.

No. Your criticisms of Uber aside, the poster notes that this lacks the network effect that Uber uses.
