The company has already been sharing its data with city officials since 2017, but that was to help with urban planning efforts.

A spokesperson wasn't shy about the main reason for the experiment: it's about making an informed choice about your method of transportation, including when you'd be better off using a bike or scooter. While a car might get you downtown in comfort, it might be faster and cheaper to pedal your way instead. Uber won't even necessarily mind if you take the bus, since it has a partnership with Masabi to offer access to mass transit options in some cities.

There could be more cynical reasons for the move, of course. More realistic traffic estimates might lead to patient passengers who'd be less likely to catch a Lyft. This also reduces Uber's dependence on Google, which could be helpful as competition heats up between the two. It could develop traffic technology on its own terms, rather than waiting for Google's help.
