Stamford plans to release self-driving shuttle buses as early as next year.

The self-driving shuttles will follow a fixed route from the train station down Tresser Boulevard.

Officials say back-up drivers will be there just in case cars or pedestrians get in the way, which are just some of the potential pitfalls the state's Autonomous Vehicle Task Force is already looking at.

State Sen. Carlo Leone says they are looking at traffic laws, and who is liable in a crash.

Connecticut's new transportation chief says roads themselves will have to change.

Consumer Reports tested self-driving cars from its trial track in Colchester. They say Connecticut will have to redesign its roads for self-driving cars to work.

"To really make this work, you need the infrastructure - the road itself - to become 'smart,'” said Leone.

New 5G networks will let cars to talk to teach other and the road itself.

Stamford is learning about the technology from the self-driving shuttle in Providence, Rhode Island which launched earlier this year.
