A new AAA survey shows most U.S. drivers are still either afraid or uneasy about the idea of fully self-driving vehicles. State AAA spokesman Nick Jarmusz says 66 percent of drivers expressed fear of full self-driving vehicles, while 25 percent were uncertain. Jarmusz says the fears are mostly driven by numerous well-publicized incidents where drivers lost their lives in car crashes because they were led to believe their vehicle could drive itself. Jarmusz says the transition to autonomous vehicles must be done slowly and with full transparency.
