It'll make your day better, guaranteed.
The only thing more satisfying than spotting a rare, insane supercar being taken out on the open road and driven, is perhaps seeing an even rarer, even more insane hypercar in a similar situation. And when it comes to the Koenigsegg One:1, it doesn't get any more rare, or hyper, or insane, than this. The One:1 was spotted on the road in Sweden by YouTube user GTBOARD, who was lucky enough to catch a glimpse of it and even keep up with it on the highway.
