Back to the Future

As a youth I worked as a brewer’s drayman assistant and more than one driver lamented the days of the horse being past. It had been common practice to throw the unconscious drunken drayman on the cart and let the horse find its way back to the yard. Instead they had to drive a 4 ton truck while drunk. So if full self driving trucks make a come back then congratulations, you’ve successfully replicated the technology of the horse and cart.
