A public feed of all rides? Who in their right mind would want the world to know that they are leaving for the airport? Or publicly give out their home address?
It's a great idea for Taxi's (the radio).
I'll hold my opinion on this software.
I also don't know why the parent post is getting down-voted. HN can be harsh.
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.
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.
