This is an active system, which means it has to be actuated ON TIME to work (as opposed to the passive Halo system). Very difficult I would say. Using a detection method to "see" objects that may impact the driver to move the driver down would probably lead to some unexpected behaviour (assuming the whole process is fast enough).
Imagine the driver in a 250km/h corner and suddenly the seat moves because of a plastic flying in front of the car.
I like the fact that you tried something new, but I don't think it would work.
As with the halo, this device would not be for small debris. I wrote the OP in haste and left out some of my thought process. You are correct though in your concerns regarding an active system. That said, consider the complexity of cars these days, a myriad of active systems all bound together. Do the gremlins lurk in those as well? Any one of them fault in the middle of Eau Rouge and it's "Eau Maird!"
The question remains, even if the injection seat is intended for large objects, tires, cars, trackside stuff: how to trigger it?
Could be driver controlled, for times when they are in an out of control slide and can see an impending impact.
If a driver cannot trigger the device, automation jumps in. One idea is to embed proximity beacons within known massive objects on the track. Wheels or uprights, chassis, support vehicles, etc. These could be detected car-to-car from within a short range, and also tracked by FIA HQ. A live safety network, informed by gps and these beacons and their sensors. When impact trajectories develop, the system would trigger.
Vertical acceleration or excessive yaw & pitch could also trigger it, indicating becoming airborne or rolling.
Optical or radar detection may need to be quite sophisticated as you elude to, but there is much industry currently focused on autonomous vehicles. Perhaps their expertise can be contracted for such an application.
Thanks for the feedback.
