Script for the recording:
We're going to e more and more automation as time goes on. Making a car that goes more than 100 km/h isn't a huge engineering problem — but human drivers can't respond fast enough to make tho speeds safe. Personally, I'm all in favor of letting the car drive itlf. I'd much rather trust my life to the efforts of engineers and programmers than the angry, sleepy, distracted, incompetent, drunken people who are behind a lot of wheels now.
It's often been said that anyone could have predicted the automobile, but only a science-fiction writer could have predicted the traffic jam. Well, here I am predicting the end of traffic jams: computer-controlled cars won't get in each other's way, and they won't slow down as their drivers gaze at accidents — in part becau there will be many fewer accidents, and in part becau the pasngers in the car will be able to get a decent look without the car going at a slower speed.
There really are a lot of plus to the lf-driving car: you can sleep, drink, read, watch TV, do work — whatever you want — while getting safely and efficiently to your destination. For my money, we can't make the transition soon enough. "Road rage" will be a thing of the past; there's no reason driving should be frustrating, or why car accidents should be the leading cau of death of men under the age of 25.
Still, there will be a desire to get out on the open highway and just drive — people do enjoy that, and it won't entirely disappear. But in the future when we talk about hybrid cars we'll mean cars that can be both lf-driven and controlled by a driver; the terms "manual" and "automatic" won't refer to transmissions but the totality of operating the vehicle. So, yeah, you can get out on the highway when the mood strikes you — but most of the other vehicles will still be driving themlves.
