Why on car radio and home stereo, me push AM, me get one set of
frequency,
and then when push FM, me get another set of frequency?

Me not know why. Me not understand.

I get the impression that this may have been a Troll post, but it really
is a valid point.

It is far too common to refer to a broadcast band by the modulation method
used rather than the
band of frequencies used. Here in the UK we refer to those radio
broadcast bands as "MW"
(Medium Wave) and "VHF" (Very High Frequency). These bands are also
commonly referred to as
"AM" and "FM" simply because the MW band uses Amplitude Modulation and the
VHF band uses
Frequency Modulation.
We also have a band called "LW" (Long Wave), which also uses AM.

Regardless of the wave length, you can transmit an AM, FM, SSB or CW signal.
MW, LW and VHF are just different frequencies.
