I've worked on autonomous vehicles for 16 years and my largest philanthropic effort is improving public transit. The common theme is being really interested in transportation and wanting it to work well for people.

Cruise was also the top funder of one San Francisco's recent MUNI funding ballot propositions (which just barely failed). You can certainly have a cynical take on that, but they still did it.
