This is BS. The news was debunked two weeks ago and the researchers involved put under the microscope for their ridiculous media claims which conflict with their own data. Old news I really can't be bothered to link to any of this stuff.
oh ok here is one article:
The media got it wrong: Bikeshare programs don't increase head injuries - Vox
whats surprising / not surprising is that Fox is running a two week old de-bunked news story without mentioning the follow up stories. Pathetic - almost everything coming out of those anchors' mouths was a lie.
