One unintended consequence to driverless cars and their growing ability to avoid traffic infractions is that the money from tickets often goes to fund law enforcement. Of course, fewer road accidents and, say, the decriminalization of drugs, would lead to less of a need for a large police budget. From Colin Neagle at Network World:

“Shortly after the state of Washington voted to legalize recreational marijuana late last year, opponents made a very interesting, if somewhat counterintuitive, argument against legalized pot – law enforcement would miss out on the huge revenue stream of seized assets, property, and cash from pot dealers in the state.

Justice Department data shows that seizures in marijuana-related cases nationwide totaled $1 billion from 2002 to 2012, out of the $6.5 billion total seized in all drug busts over that period. This money often goes directly into the budgets of the law enforcement agencies that seized it. One drug task force in Snohomish County, Washington, reduced its budget forecast by 15% after the state voted to legalize marijuana, the Wall Street Journal reported in January. In its most fruitful years, that lone task force had seen more than $1 million in additional funding through seizures from marijuana cases alone, according to the report.

Naturally, this dynamic is something law enforcement either is or should already be preparing for as driverless cars make their way onto the roads. Just as drug cops will lose the income they had seized from pot dealers, state and local governments will need to account for a drastic reduction in fines from traffic violations as autonomous cars stick to the speed limit.

Google’s driverless cars have now combined to drive more than 700,000 miles on public roads without receiving one citation, The Atlantic reported this week. While this raises a lot of questions about who is responsible to pay for a ticket issued to a speeding autonomous car – current California law would have the person in the driver’s seat responsible, while Google has said the company that designed the car should pay the fine – it also hints at a future where local and state governments will have to operate without a substantial source of revenue.”
