It was functional for me; there was someone reading some rather bad (in the best way) jokes, "What kind of car do dogs hate? A cor-VET". It really felt connecting, since the people replying and cooperating on the channel are all going through the same experience. I saw a comment above about having a radius visible for the talkie (if there is a radius?)

Oh, and +100 points for the thing being anonymous.

It works, people are shy. I had a crack at talking to some folks, more to comment on how interesting the application itself is. I wonder how the app deals with many people connected? Maybe different instances?

Think, most browsers limit number of peers to 256. Not sure what happens after exceeding the limit. Never tested, honestly.

Having 256 people on a call must be a crazy experience, but the app only connects you to other drivers in vicinity, the radius is about 100 km.
