but if it wasn't for friction, the wheels would simply spin on the ground.

that's not what slows you down. Friction between surfaces that are not
moving relative to one another wastes no power.

But they are moving relative to one another, all the time.

not at the pint of contact. That's the whole point

Unless you are in a wheelspin mode

Ineptocracy

(in-ep-toc’-ra-cy) – a system of government where the least capable to
lead are elected by the least capable of producing, and where the
members of society least likely to sustain themselves or succeed, are
rewarded with goods and services paid for by the confiscated wealth of a
diminishing number of producers.


There is always "microslippage" between wheel and road. Even more when
cornering.
