Yes, but they aren't building heat up in those tires by flexure during
those maneuvers. They are simply loading each side of tires down on the
road. There is a bit of flex, for sure, but the majority of the heat comes
from road friction.

In your dreams. Wheels were invented to eliminate road friction
in the forward direction and retain it laterally.

Exactly my point, when the F1 racers flick from side to side, they are
loading the tires down laterally, thus building up lateral friction
from the road surface on those tires.

And to be technically accurate, wheels and tires don't eliminate
friction in forward or transverse direction, otherwise cars would
never be able able to brake. Nor would they be able to startup for
that matter as they wouldn't be able to accelerate either, since their
wheels would just spin-out due to the lack of friction.

Here's a very simple experiment and an easy proof:
Get a wire coat hanger or similar steel rod and start flexing it as
rapidly as you can until it breaks. You'll burn your thumbs before
it does.

Yes, yes, that's all very interesting but the amount of heat built up
by flexing depends on the stiffness of the material. Rubber is
definitely less stiff than metal wire.

It doesn't take a scientist to know that happens, any experienced
metal worker is aware of it.
Earth's mantle is hot because the Moon flexes the crust, plate
tectonics is driven by the Moon.

Then why isn't there plate tectonics on the Moon too? Oh yes, because
it has tidally locked to the Earth. Then why isn't plate tectonics any
less now than in the past, when the Moon was much closer to the Earth?
