DENVER (AP) — Automated cars won't be allowed in Colorado this year after a state Senate committee rejected a bill to allow driverless vehicles.

The Senate Transportation Committee decided against the bill to make Colorado at least the fifth state where automatic cars are legal. The cars are under development and are touted as safer than human-operated vehicles.

The bill would have stated that automated cars must still contain licensed drivers, and that the cars would have to have an override switch so they can be driven manually if needed.
