With a disruptive tech that still lacks widespread public trust, there remain questions of the ethics behind fully allowing driverless trucks and cars on the road. John Hooker, a professor of business ethics and social responsibility at CMU’s Tepper School of Business, told Technical.ly that this is a subject his classes discuss frequently.

“In the ethics world, we have two principles that apply to an issue like this,” he said. “One we call utilitarian principle and the other is the autonomy principle.”

The utilitarian principle has to do with maximizing benefit with respect to releasing this level of autonomous vehicle on the road. That principle should be easy enough to satisfy, he said, given the incredible danger that human-operated vehicles pose today.
