Relative to the car you are motionless. Relative to the road you are moving at the speed of the car. Relative to the sun you are moving at the speed of Earth as it orbits the sun (30km a second).
you are motionless
One point of view from which to describe motion is the observer's frame of reference. This point of view defines the position and motion of an object relative to the observer. By choosing a specific frame of reference, we can describe how an object moves in relation to that reference point.
The bike. Even though you and the bike are in motion the positions do not change.
You are not moving relative to the bicycle.

Motion parallax provides perceptual cues about difference in distance and motion, and is associated with depth perception. For example, if you are riding in a car, objects that are close to you seem to go by really quickly, but objects that are further away appear to move much more slowly.

A heavier car has more inertia, resistance to a change in motion, than a lighter vehicle. Therefore in the event of a crash the lighter vehicle will have a greater change in motion relative to the heavier vehicle; the less the change in motion, the safer.
Relative to the bus, you are moving towards the back. If your walking speed is slower than the speed of the moving bus (which it usually will be) then your motion relative to a point on the ground will be moving in the direction of the moving bus, but slower by the speed at which you are walking.
Any motion where the object moves from place to place, e.g. someone riding a bike.
You are not moving, if you are comparing to the car.
