For AVs to become a commercial reality, AV developers are starting to realize that they must learn to handle huge numbers of edge cases -- the countless high-risk scenarios which are individually unlikely, but together make up the bulk of the risk.  dRISK is solving this problem with a full-stack technology suite for training and testing AVs on the most diverse ever collection of edge cases. This product, the first true driver’s test for self-driving cars, is funded by a major grant from the UK’s Department of Transport.
