I found this TED talk on self driving cars interesting, particularly the time frame mentioned at the end that Google is aiming for. If it comes to fruition, it could revolutionize travel by the 2020s.
Personally, I’m looking forward to being able to surf the web, read, or just get a head start on emails and phone calls during my morning commute. And for long trips, if I don’t have to actually drive it, but can instead spend it playing games, watching movies, and sleeping, I can see car travel taking me much further, to destinations I currently feel the need to buy a plane ticket for.
Many people will insist that they love driving, and can’t imagine giving it up. I like driving too, when the weather is good, the traffic is lite, and I’m not tired. I have to say that those circumstances don’t happen nearly often enough these days to stop me from giving it up once I can have the same freedom without it.
