Pages 207 and 208 of the owners manual:
"Camera blocked or blinded
Clean camera or wait for it to regain visibility
One or more of the vehicle cameras is blocked or blinded due to external conditions. When the cameras cannot provide accurate visual information, some or all Autopilot features may be temporarily restricted.
Cameras can be blocked or blinded due to many factors that include:
• Dirt or debris on the camera surface
• Environmental conditions like rain, fog, snow, or dew
• Bright sunlight or glare from another light source
• Condensation (water droplets or mist) on the camera surface
Continue to your destination. This is often a temporary issue that will clear up when condensation evaporates or a particular environmental condition is no longer present.
If the alert does not clear by the time you reach your destination, check the camera surface for condensation, dirt, or other debris."
I would say that that is unambiguous. The assumption that the system have 100% uptime is just that- an assumption. It's an unfair assumption as well- no man-made system has 100% availability and 100% uptime.
