Theory of relativity in speed

Statement: You will always see more vehicles in the opposite lane approaching towards you when traveling in a highway.

Disclaimer: Something like this might have already been stated more properly and proved also. Any similarity to the original is purely co-incidental.

Proof:
Assumptions:

Assume there are 2 points A and B.
And there is some finite distance between A and B lets say it as 'x' km.
Vehicles v1 and v2 are starting from A and towards B in lane l1.
Vehicles v3 and v4 are starting from B and towards A in lane l2.
Lanes l1 and l2 are adjacent to each other with a small barricade.

Suppose v1 and v3 have started together and bit early and are traveling at a speed of 60 km/h.
Suppose v2 and v4 start together but bit late than their counterparts and are traveling at a speed of 30 km/h.

In the course of vehicle v2's journey it will not overtake v1 and so it will not encounter any vehicle in it's lane.
But it will definitely it will meet v3 and v4 in the opposite lane.

So taking this argument forward for 'n' vehicles, we can say that this theory is proved(at least I am convinced).

Hence the proof.
