The BLU founder met in person with the local Cambridge bicycle people last June (I was there) and they made it extremely clear to us that (for legal reasons) they will never share their data with us. I'm talking about not just a heatmap in a browser, with this data https://loudbicycle.com/bb/download you can make visualizations like this:

Also - BLU does great work manually reporting top offenders and doing many other things too. The 311 reporting that BB does is not the same, it is automated and goes through official city channels that is _supposed_ to be result in immediate enforcement. Again not meaning to cast shade, just literally recounting what was told to me directly face to face.
