Driverless vehicles no longer exist solely in spy movies and futuristic dreams. In fact, Solano County streets are one step closer to a future that features these self-driving “robotaxis.”

Waymo is testing a Gemini-powered in-car AI assistant, per findings from a 1,200-line system prompt. The assistant can answer general knowledge questions, control certain in-cabin features, and more.

Waymo has begun offering select riders access to driverless taxi trips on Los Angeles freeways, expanding its autonomous service beyond surface streets.

Waymo has long maintained a strict rule: Passengers are not allowed to sit in the driver’s seat or touch the vehicle’s controls. The policy is outlined in Waymo’s rider guidelines and onboarding materials, which explain that the front seat is reserved for trained personnel and off-limits during public rides.
