What’s the best route from Las Vegas to Yosemite National Park?

I’m intrigued by the future of self-driving cars. Maybe I watched one too many sci-fi movies, but I feel like it’s the technology that’s going to change the world, much like the internet. I live in Atlanta, so my only worry is that the government is going to regulate them too much. In Georgia, are self-driving cars legal?

I’ve looked at fuel economy for some cars that I’m interested in buying. Aside from some hybrid models, every car has better fuel economy on the highway. This doesn’t make a ton of sense to me. Do you actually save gas by driving faster?

I was in an accident last night, and I didn’t get the other party’s insurance information. I realize now that I need it. How do I find out the other person’s car insurance information?
