re: #115 Sherlock Hound

“Various levels” is doing a lot of work. Either the capabilities are controlled, or the environment is.

I suspect it will be a combination of both. And then I expect some places to advertise it. “Would you like to be able to see the sights when driving to your destination? Our roads are properly maintained - smooth and properly striped - so that you can let your car do the driving so that you can enjoy the view.”
