When Colorado lawmakers in January unveiled a bill designed to increase transparency for ride-hail and delivery drivers, the tech companies sounded a cooperative tone. “We’ve long supported many of these ideas,” an Uber spokesman said. “Fair deactivations and pay transparency are important issues,” a Lyft representative said. But three months later, those companies and other business groups are lobbying heavily against the legislation, warning consumers about “unprecedented fees” and safety concerns that, they argue, would allow dangerous drivers to stay behind the wheel. Now, with just a week left in the legislative session, the future of the bill is murky.
