Bird works very well here in Tel Aviv! I use them every day. However, I've never seem them work well in other places.
I see more electric scooters in the bicycle lanes by the boardwalk than bicycles, by a factor of 2x or 3x.
I'm not sure the Bird model will work everywhere, but in "beach towns" or college campuses, etc, it's a good model. It's probably overvalued, but the concept of a "ride share dockless scooter" isn't always bad in some places.
