Magna isn't fully severing ties with Lyft, in which it invested $200 million in 2018, but the self-driving partnership seems to have been impacting its bottom line. They'll keep working together on other autonomy-related software and hardware. Lyft has also collaborated with Waymo on autonomous cars.

Ultimately, Magna doesn't think there's big enough potential in autonomous vehicles in the medium term. It sees more opportunities for growth in the assisted driving market (up to Level 3 autonomy) over the next five years.

CEO Don Walker told reporters that the industry is getting "more realistic" about how long it'll take before autonomous driving really takes off. As such, Magna plans to invest "where we're going to get a higher volume," CFO Vince Galifi said.
