All cars including the prototypes use a version of Corvette Racing’s digital rear view mirror and radar system. Started last year. 

I saw one of these doing a track day weekend during the 2016 Indycar Race at Watkins Glenn, however that was just the tip of the iceberg when it came to insane race cars that day as someone there had in his private collection a Corvette Daytona Prototype. It was the craziest thing I ever seen.

This mine, I will be in the Dominican Republic on Christmas
