So far, more than 10,000 people have signed Uber's online petition to sway state legislators to back bills by Barnes and Sen. Bill Ferguson of Baltimore that would establish a new class of transportation services, with regulations modeled after those of California and Washington, D.C. Both Uber and Lyft have testified in support at House and Senate hearings, as well as lobbied lawmakers on the need to create new rules instead of lumping them in with cab companies. The bills have yet to get a committee vote.
