That is the ultimate goal, but we're a long long way from that point, and when we do get to that point, it's likely that all the vehicles on the road will be automated and communicating with each other so if there is a malfunction, other vehicles can avoid it.
In the near future, you'll be sitting at the wheel ready to take over.
There's two types of Google cars. The ones you are talking about that are more for demonstration than actual road usage - that are limited to 25 mph because they aren't real cars.
And then there are the real cars that are navigated by software but still require a human driver. They are not restricted to pre-mapped roadways. Most car manufacturers are currently working on these types of cars.
When the Google car can't determine what to do, it hands things over to a human driver.
Then the programmers go in and study the situation and program a way so that it doesn't happen again - if that's possible. This is how they've been developing the car for the last 10 years - trial and error. From what I've seen, Google cars can do fine with most of the situations you've described.
You can't copy a performance, but you can copy the words underly a performance. The script you're performing from is tangible - that's why you have to get rights to perform a play, or why I can't just buy a movie script and perform it live without permission. You need a license to perform written works that are meant to be performed, like songs and plays, but you're free to copy non-tangible things like choreography.
Probably because every one of them has stuck something in that bill they want to get passed. They don't care about the rest of it - they just want to make sure their donor's wishes to become law so they can get money for their next campaign. They aren't politicians. They're professional fundraisers.
