It is well known that driver-less cars will be coming. The only question is when. A number of automakers are working diligently on prototypes, including Audi, Toyota and Mercedes Benz. In fact, Silicon Valley tech giant Google is also in the running for an autonomous car. In fact, automakers already have elements of self driving cars in today's vehicles such as adaptive cruise control, park assist functions and automatic braking functions.
While many automakers pledge to have fully autonomous cars by the end of the decade, that opportunity may not be up to them. State regulators must develop rules for the operation of autonomous vehicles, especially for testing, and these rules are slow to develop.
