Self-driving cars and other emerging technologies are going to cut into municipal budgets nationwide, a panel of futurists says.

Imagine this brave new world:

• Autonomous cars that never speed, never run red lights — and owners who never get popped for drunken driving or pay a dime for traffic tickets.

• Robotic vehicles that deliver people and goods anywhere — and choke off income taxes from displaced taxi drivers and delivery-truck drivers.

The financial impact of driverless cars represents just one of many ways emerging technologies will disrupt local governments, according to the authors of a report published by the Brookings Institution, a non-profit public-policy organization based in Washington, D.C.

Technology already is affecting social behavior, the authors wrote.
