Both General Motors and have ambitious goals to commercialize autonomous taxis in some way, but after teaming up more than two years ago, with the former investing $500 million in the latter, it seems they’ll no longer be pursuing that endeavor together.

The plan originally was for GM and the Uber competitor to eventually co-develop an autonomous, on-demand ride-hailing car network. GM President Dan Ammann got a seat on Lyft’s board, GM would provide Lyft drivers with vehicles, and Lyft would get venture capital financing from the automaker.

Lyft, meanwhile, jumped headfirst into the autonomous car race in 2017, partnering up with several companies to figure out ways to introduce self-driving cars into its ride-hailing network. Some pilot programs are under way, including .

With much of the auto industry teaming up to figure out how, if at all, autonomous cars can work, I think many expected GM and Lyft’s partnership would persist, given the high dollar amount the automaker dumped into the mix. But, alas, .
