I'd love to see some of the tire wera data that Waymo has accumulated. Despite being heavier vehicles, I bet they do well on tire wear from no hard stops or starts, driving the speed limit, keeping properly inflated, and (I assume) optimizing driving to maintain momentum (e.g. not accelerating into red lights like I see so many human drivers do).

Have you experienced waymo in SF? It actually drives faster than regular folks and brakes much more harder because of that. The speed limit doesn’t apply to the streets of San Francisco and it typically accelerates to the limit as fast as possible (especially electric).
