I personally cant wait for self driving cars. Thats not to say that i want to buy a self driving car, i do not!
First lets separate transportation from recreational driving, which are two completely different things. Its hard to make any kind of argument for self driving cars when talking about recreational driving, so ill just leave it alone.
Most of peoples time spent in cars are spent as transportation. You are in traffic, waiting on other meat bags to get the hell out of your way to get from A to B. You are wasting your time sitting behind another car staring at its rear, then doing what you want to do. Its not fun, its depressing, annoying, stressful, etc, etc. Even when you aren't sitting behind someone, you are doing a menial task of following someone in a dreary highway setting.
Its because of that that we have so many accidents caused by talking on cell phones, or texting on them, or doing whatever on them. Most of the driving is boring/menial, and with humans thinking they can handle it when they cant, they let their attention drift. Face it humans suck at driving in these situations. They might think they are great, and its so menial of a task they they will be fine, but they aren't.
Self driving cars are perfect for transporation. You get in the car at point A, do whatever you want, and then exit at point B. You you to talk on the phone, text, play games, do paper work. Go for it, whatever you want. You get back free time wasted in traffic.
Of course who wants to own a car they cant drive? Might as well just call a taxi right? Yep! You are right! So, there is no point in buying a self drive car. Better to just have a small network of them. You get in them at point A and get out at point B. The car drives off for the next person. Now think of the benefit that brings. Most cars spend 99% of their lives parked. Their utilization is utter crap. Change that so the cars are spending most of their time moving, and you get tons of cars off the road. Traffic congestion goes WAY down when you remove a small percentage of cars off the road. There is a certain capacity that a road can handle before it starts to slow down. If that number is say 100, just going to 120 might cut the speed in half, 150 might stop it all together. (made up numbers). Even without less cars, you can potentially fit many more cars on the road at speed if they are self driving and can tell eachother what they are planning on doing. With communication, you can tightly pack cars together in traveling packets at speed safely.
Add to that the fact that humans are slow to react. A computer out think you, it can out see you, and it can out react you by orders of magnitude. As computer processing power continues to increase, it only becomes better. Humans never will.
So, lets see, you get more free time, you get to your destination faster because of less traffic, and you have less accidents because computers are better at following the rules and can react much quicker then you ever can. .... Who wouldnt want them to arrive as fast as possible for the daily commute.
I personal want to be able to get in a car at X time, have it take me somewhere while i screw around on my tablet/phone/whatever. Get out at point B, and have the car go drive off and do whatever(which would be driving others around) while im working. Then have it there waiting for me when i get off work, get in, screw off on my tablet/phone/whatever again, and then get out at home.
Or even better. How about its friday night, im off work, just had dinner and say its 10 pm. I throw a bag in the car, lie down go to sleep. And by the time i wake up im 500 miles away at a vacation resort. I spent 2 days there having fun. Then go to sleep in the car again on sunday night and arrive at home in time for work. I didnt have to waste 16 hours of free time driving 1000 miles on the weekend, but i got to enjoy a full weekend somewhere else. Sounds great to me!
