An artificial intelligence chatbot designed by a 19-year-old Stanford student appealed over 4,000,000 in parking fines in just twenty-one months, The Guardian reported. The AI is at the heart of a free service called DoNotPay that was designed by London native Joshua Browder to help users contest parking fines. After racking up 30 parking tickets in and around London when he was 18, the self-taught coder decided to help his fellow parking-challenged motorists with a program that would help them navigate the ticket appeals process. "I think the people getting parking tickets are the most vulnerable in society," Browder told The Guardian. "These people aren't looking to break the law. I think they're being exploited as a revenue source by the local government."
