It can take a great deal of time and money to map just a single city, much less the world. Crowdsourcing and aggregating every automakers’ mapping data would make a significant dent in the time and resources companies are spending on charting the world’s streets, according to Mobileye co-founder and CTO Amnon Shashua. The problem is, auto companies have long been reluctant to hand over their data to competitors for fear of relinquishing any competitive advantage. That’s increasingly becoming the case as more players join the race to build and deploy self-driving cars.
