The car reference frame
starts to be accelerating for a reason as well.

Motion equations describing movement in accelerating frames
formally include the fictitious forces, to keep formula
vec F = m . vec a
valid even for accelerating frames.

To keep a body not accelerating in accelerating frame,
the same force as the fictitious one but the opposite
has act upon the body.

For the rotating accelerating frames like the natural Earth frame,
there are 3 fictitious forces.

Centrifugal force, related to the body position.
Coriolis force, related to the body velocity.( the most known )
Euler force, related to acceleration of rotation, negligible for Earth.
