Lesser drivers (the vast majority don't have the talent for F1 (although some might make up for talent with money)), slower simpler similar cars running on GP tracks will of course mean that feeder series' will always have more 'incidents'.
Unfortunately people think that incidents = a good race, a view I do not subscribe to.
In F1 there is the best drivers, in the most advanced cars, at higher speeds, with more traction, better brakes, better aero (and hence worse for the following car), very dissimilar cars. F1 has never, and never will be what the masses want. People who think old F1 was more exciting to watch are sadly looking at it through rose-tinted spectacles. It's always been 'dull' to those not interested in the finer points of motor racing. To those who are interested in the finer points (the technical, the political, the skill etc) then F1 remains the pinnacle.
