The car may be a reference frame, but it is not an INERTIAL reference
frame.  While velocity may be relative, acceleration is not.

Also consider the car bolted to the deck of a spinning merry-go-round.
Occupants will see other "strange" forces.  It's another non-inertial
reference frame.

Heck, just think of the car just sitting there on the road.  There's 
another strange force pulling everything down.  It's called gravity, and
the surface of the earth is non-inertial for that reason.
