Sure, my understanding is that they collectively share data, and this is combined with central mapping. On net, yes, they are sensitive to features of the environment and via central coordination maintain a safe map of it. The mechanism there heavily relies on this background of sharing, mapping, and route planning (and the like) -- which impacts on the ability of these cars to operate across all driving environments.
