President Donald Trump, apparently enamored by the pint-size kei cars he saw during his recent trip to Japan, has paved the way for them to be made and sold in the US, despite concerns they're too small and slow to be driven safely on American roads. "They're very small, they're really cute, and I said 'How would that do in this country?'" Trump told reporters on Wednesday at the White House, as he outlined plans to relax stringent Biden-era fuel efficiency standards.
