Fair enough! I watched the video again and still dont understand what the problem is or what's being solved, but yes - there's the act!

It connects the dots through - Amazon seems to be claiming their drivers are exempt from something due to being contractors, and this bill will enforce those undefined somethings to be enforced.

> This bill would require operators of certain warehouses and storage facilities from which goods are delivered to final consumers in the City to obtain a business license from the Department of Consumer and Worker Protection. This bill would set forth the conditions of such license, which would include safety, training and employment requirements. This bill would also set forth enforcement options, including those available to the City and to workers.

The bill text itself seems to be more about hiring / firing practices than trucks.
