A fence and over&#x2F;under animal crossings would probably deal with the non-flying animals.  Birds require a bit of intervention sometimes.<p>I wonder if anyone has done a paper on how fast &#x2F; how dense you can drive automated cars while maintaining a decent safety margin.<p>Also, different makes of automated cars are going to be a pain in the butt for the system.  I&#x27;m sure the Kia and Ferrari are going to want to go different speeds.
