Posting that history was an excellent idea. Simply looking at the
list is an education. At so many stages the question "WHY?" seems
unanswerable.

For instance, "safety" as a reason for changing engine reg's has
never made sense to me. The 4500cc limit in 1950 seems perfectly
sane, and I imagine today's engineers could produce a nice powerful
atmospheric motor that would live long. What is the math regarding
displacement? Doesn't a big-inch motor necessarily rev slower than a
smaller one? (Top fuel engines, despite a flat-out design life of
about 10 seconds, and with supercharging, never exceed 8000rpm.)

I like one poster's suggestion about "all-weather" road style treaded
tires, if they won't give us slicks. Someone remind me why slicks
were "bad" for racing or safety or spectacle?

Anyway, thanks to the poster for that chart!
