http://alttransport.com/2010/10/the-google-car-that-drives-itself-successfully-tested/ In America. Working. Will only get better. Guy at work managed to run over his 3 year old with his car ~ as it was parked in his driveway. Fortunately it only ran over her hair.
They said "operational tests with the public within 10 years" and "within 20" for deployment. Fourteen years and we're not even at operational tests.
It's nice that Google is pushing the technology ahead but it doesn't matter unless it can get to consumers.
On the co-worker: good thing it was only her hair that was run over. Some kids (or pets) aren't so lucky. The sooner we can get people out of the equation the more efficient and safe vehicular travel can be.
