Google cars actually drive on roads though, and the only reason for human intervention is should the car fail.  Early tech that can kill people requires a person standing behind it.  It looked like, to me, that the demo of that car was one that moves slowly and does little.  It can drive in the rain because it's not dealing with the sort of rain a regular car would.<br><br>I wouldn't even begin to call this little thing comparable to the google car.
