Canada’s leading developer of self-driving systems has unveiled its new strategy for teaching autonomous vehicles to perform safely: It’s basically a driving school for robots run by another robot.

More precisely, Waabi Innovations Inc. has developed an artificial intelligence-powered simulator that not only recreates the driving experience but challenges an automated driver’s weaknesses so it learns faster. On Wednesday, the Toronto-based company announced its simulator will provide a level of experience that would otherwise take thousands of autonomous vehicles driving millions of miles on the road to acquire.
