&quot;Human + computer will be a safer, more reliable alternative.&quot;<p>Unfortunately, there&#x27;s a cliff where if you aren&#x27;t stimulating the human enough, they stop paying attention. They can&#x27;t help it. Their neural architecture is fundamentally structured to do that and merely trying not to isn&#x27;t going to cut it.<p>We can&#x27;t have automated cars that 98% drive autonomously but beep when they need help, <i>right now</i>. This could work if the car can <i>reliably</i> predict when it is going to need help in 10+ seconds, but I&#x27;m not sure that&#x27;s practical. (Which I phrase that way on purpose... maybe it is. I&#x27;m just not sure. Would certainly take a lot of work and some very conservative automated driving.)
