You are right about a single vehicle crash hitting a fixed object - the weight of the vehicle is less or no advantage.
A Fact? That's about the most far-stretched claim I've heard. Are you an engineer who can prove this? Are you 100% certain you are correct?

Unless you're talking about a Hummer or a truck, I dont understand how a better structurally engineered car at 1250kg can't out-crash a 1450kg or 1500Kg car. Have you considered the fact that an A-Class or a Yaris is so safe not only due to the passive safety features and/or has sound structural engineering, but perhaps because its specific shape (like an egg) gives it better crashability?

As I already said 'may be' in a 2 car crash the heavier one should have an advantage over the lighter one but for me, I would not be as conclusive as to claim it as 'a fact' just because you think it is simple physics to you. To me, its more like a case by case scenario.

Perhaps A is safer than B during a crash. And B is safer than C in a 2 car crash. Due to the different impact points, heights, etc, it is impossible to conclude thatn C can't actually out-crash an A.
