Actually, if you ride against the Earth's rotation the car will get
heavier until a certain point (where it stands still) and then it will
loose in weight again.

No, you can easyily see the road is moving by speeding up the car to
it is most heavy. Then the car stand still and the road is moving
(more than 1500 km/h at equator).
