Legislation to test autonomous vehicles in Illinois may come up again in the November veto session, though the lead sponsor of a pilot bill says there’s still a lot of work to do.

Autonomous vehicles, or AVs, are motor vehicles that have an automated driving system.

But state Rep. Kam Buckner has called for a formal framework, through House Bill 4663, to test and deploy self-driving cars in the state.

But autonomous vehicles at high-congestion points may worsen traffic, said Dany Robles, senior legislative director at the Illinois Environmental Council.

The Northern California region has a program that incentivizes autonomous vehicles to solve the first- and last-mile problem.
