Almost all of the innovation that's going on in light, piston airplanes today is happening in the experimental category. I've got newer, better, and safer avionics, sensors, lighting, and engine systems in the E/A-B category airplane I built in my garage than I would on a 1970's Cessna. The richness of inputs I have in the cabin, including a big moving map GPS, ADS-B traffic, satellite weather, carbon monoxide detection, a vast array of engine monitoring signals, AOA, and so on provide so much more in terms of safety and situational awareness. Pilots in the USA are truly lucky that we have this option.
