So you wonder what's going to happen to general aviation because of the
high prices of avgas? Acquire yourself an aircraft which will fly on
auto fuel.

I have a lovely 172G with autogas STC and will sell it to you for a
reasonable price.

Why fly a 172 when you shortly will be able to rum the big iron? There's a
Lycoming TSIO-540 running in OK on avgas.

I'll believe that when I see it. Test stands are inadequate to
simulate flight conditions. In the meantime only low-power,
lower-compression engines are legal for mogas.

Cylinder pressures, heat, and many other considerations in a TSIO-540
don't make it a good candidate for high-volatility mogas. I don't know
of any injected or turbocharged aircraft engine which could safely run
on mogas.

We have big-engine aircraft like Pathfinders and Bonanzas on our field
with vapor-lock all the time, and that's with the blue gas.
