Government regulation usually comes along after all is said and done, because in a democracy a lot has to be said and done before the Bureaus of Funny Walks can decide how to proceed with new regulations. I'm with Blick, in that I believe that too many people want to blame the tool when they hit their thumb with a hammer, and many of them are elected officials.
I said this before, and I'll probably say it again. Too many people are persistently unaware of the dangers they face every day. They wake from their slumber, rush to get dressed and stumble out into the world expecting Civil, Electrical and Mechanical Engineers to protect them in their transport, and building infrastructure, while they drive recklessly, stand directly in front of aging microwave ovens, and roll their eyes at safety officers trying to enforce rules. These people can live for a long time, even in todays dangerous world of 2 ton vehicles in close proximity with multiple instances of 40 tons of freight traveling at 75 mph. But just because they can't safely operate a 3 wheeled ATV, doesn't mean legislators should take away all 3 wheeled ATV from the public. That's my opinion and I'm sticking to it.
Engineers have to anticipate every possible scenario to make a machine foolproof, and that is impossible, especially when it comes to transportation vehicles. The streets and highways evolved from wilderness trails to accommodate wheeled transport, with a different set of rules legislatively formed in each state. Topography and land ownership often create unique situations where design compromises are made. In the early stages of autonomous vehicle development, anyone who expects to sit in the backseat while the car does it all is going to become part of the statistics of the history of the industry. And, even if you're in the front seat, if you abdicate your responsibility entirely to a computer, you may as well get in the backseat, kiss your rosary and say a little prayer of hello to your maker.
