self driving cars will save a lot of lives.
It wouldnt' take much to be a better driver than most people.
30K people die in car wrecks yearly
250K are maimed.

True, but i think in order for it to be totally effective, everyone needs to adopt it. Afterall, if several bad and reckless drivers decide not to use a self driving car, they can still cause accidents. Either that or autonomous vehicles will have to learn how to predict bad drivers actions and be able to react immediately. I do think that it could lesson the number of accidents though.

Nothing is totally effective.
Go with the probabilities.
Risk management.

We had trials and trials and I think it will happen sooner for Singapore though some unfortunate news recently.
