Cruise, a self-driving subsidiary of General Motors, announced today that it is acquiring Voyage

, a self-driving startup. Its the latest in a trend of consolidation in the industry.

The self-driving industry is consolidating, and the leaders of a trillion-dollar market are fast emerging, said Voyager co-founder and CEO Oliver Cameron in a blog post. After being intimately involved with the AV (autonomous vehicle) industry for the last five years, I can say with certainty that Cruise with its advanced self-driving technology, unique auto-maker partnerships, and all-electric purpose-built vehicle with no human controls is posed to be the clear leader.

GM-backed Cruise is relatively well-funded compared to Voyage. It operates its autonomous vehicles in San Francisco it began testing fully driverless cars

late last year while Voyage has been testing mostly in smaller retirement communities like in San Jose, California and The Villages, Florida. Voyage is a startup that spun out of online education company Udacity.

Cruise itself has teamed up with Microsoft

recently to help accelerate its research. Other notable self-driving partnerships include Amazon purchasing Zoox

, Apple buying drive.ai

and Uber selling its self-driving division

to Aurora.
