Just found this ad through APTA‘s members-only Knowledge Gateway, from Passio Technologies. Ignore the words. Look at the picture.
But that’s not a photo of microtransit. That is a photo of an elite fixed route commuter bus called Leap that existed in San Francisco for a few months in 2016-17. I wrote about that project here. You’ll recognize the bus from the video at that link. I wonder what the folks at Passio were thinking.
