If you find yourself in a miltary vehicle with the ability to loft weapons into the sky, it’s a really top idea not to be around when they plummet earthwards again.
Today’s invention is a guidance system for such antiaircraft vehicles which predicts where the shells will go and then guides the steering so that, when travelling at high speed, you don’t drive under your own bombardment.
Another mode of operation would be to have the vehicle set a course and use that to dictate which directions you could fire in, but I suspect that might not be so useful.
