It'll also let you "race" against ghost cars from other people's real-world laps. Just as amazing—and potentially game-changing for the weekend driver—is that the system can use virtual cones to create any course. It's good for both teaching novice drivers things like emergency lane changes, and for autocross events, where the entire course can be drawn on your HUD.
Check out this video of the demonstration, then hope this makes it to production some day.
