Simulated: the lot, cars, people, the car's roof-mounted 360° camera, and the car's own driving and braking (which use the simulator's exact distances, as a real car's sensors would). Real: every judgment and decision, asked live of TypeSafe's Jev through its API on frames rendered moments earlier, from a scene you built. Open any call in the log to see exactly what Jev was sent and what it said. Not affiliated with or endorsed by TypeSafe. What you type in the idea and question boxes goes to TypeSafe with the frame.
