> Uber has all kinds of crazy promotions, like paying a flat $6 per ride for a whole month, or paying $25 up front for ten rides, no matter how long they are. Of course, there's also surge pricing that everyone knows about.

Lyft frequently gives me offers like "10% of your next 10 rides" and "25% off this weekend!". I think it's because I'm only an occasional rider (1/month or so unless I'm traveling). Uber does not give me any promotions.
