How can you trust a thing that doesn't exist? It's certainly understandable why people might hedge their bets. It's a lot to ask to get commitment to something sight-unseen. I have faith that the trust will arrive soon after the technology does. In the article, they state that Google thinks it will be 30 years before cars will be fully capable without steering wheels. If I were a survey respondent, I wouldn't want to wait that long to get my next car either.
