As much as I hate Cambridge I'm having a hard time finding fault with this. Bike lanes fit their needs really well.
Are there scooter companies in Cambridge? I've been hoping they would spur some major cities to invest in bike lanes but I'm not sure if that's the case here. Either way, solid win all around.
As another commenters mentioned they were there briefly before the .gov told them to get lost. The other thing about MA is that it's highly totalitarian. The government is mostly benign and the single party nature of the state means it doesn't cause too much discontent but trying to pull an Uber and provide a service that has popular support before the regulators can kick you out doesn't really work in MA because the people have little choice in the manner, the .gov can just say "this isn't good for you" and that's the end of it.
