The new rules come after travelers complained cab drivers were overcharging for rides amid the regulatory upheaval sparked by the app-based services, Salt Lake City International Airport spokeswoman Bianca Shreeve said. [...] the companies complained the council's rules requiring background checks, insurance and inspections were still too burdensome for their part-time drivers who might work only a few hours a week. The state rules, supported by the companies, require drivers to be covered with at least $1 million in liability insurance, but allow the companies to do their own background checks and vehicle inspections. Anderson, a former Salt Lake City mayor, said the ride-hailing companies should be regulated just like taxi companies to level the playing field, keep riders safe and allow cabdrivers to make a living.
