Self-driving cars will cost cities, futurists say

Self-driving cars and other emerging technologies are going to cut into municipal budgetsnationwide, 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.
