Piloting planes! A Cessna usually is 50+ years old (since regulations apply for newer planes), instruments are awfully analog, and a good share of crashes happens by fly-into-IFR. Get a helmet: You’ll still get the analog instruments + warnings if they go outside range + 3D navigation map + horizon + a circle around far-away planes that might fly towards you (TCAS) + weather map. All of these are today routine causes for accidents. All that in the $3500 helmet that you also use for work. Plus you can look at your feet and see the terrain.
Could even put dinosaurs in there.
