This video showcases a proof of concept demo of an in-game collision detection and avoidance system on the ETK800 vehicle. The system is designed to only intervene when applying 1 g-force of deceleration would bring the vehicle within 2 meters of the object you are approaching by the time your vehicle's velocity matches the approaching object's velocity. Provided the vehicle is able to see the object at a range of 150 meters, this collision avoidance system has been able to avoid collisions with a (straight line) approach speed of up to 95 mph (153 kmh).
It uses raycasting for the static environment and some fancy game engine magic to see other vehicles.
oo i can't imagine how complex that is, nice to see it's not using the lazy route with nodes maybe this concept could be used to make parking sensors as well?
