A team of researchers in the UK have taught an autonomous car to stay in its own damn lane in just 20 minutes -- an impressive feat considering I know a few human drivers that couldn't achieve that in their lifetime.

Road rage aside, the team at Wayve, a company founded by researchers from Cambridge University's Engineering Department detailed their "reinforcement learning" algorithm in a blog post on June 28. The algorithm, in tandem with a human safety driver, taught the car how to remain within a lane over a period of "15-20 minutes."
