Waymo's self-driving taxis refuse to carry extra passengers.

A recent TikTok video shows five passengers attempting to squeeze into a Waymo self-driving taxi, but the vehicle informed them via loudspeaker that nearly 30 cameras inside and outside the car could clearly see each person, and it would not start unless someone got out. Waymo's official passenger help page states that its vehicles can only carry a maximum of four passengers, excluding the driver's seat.
