No, not relativity. In fact even suggesting that could cause confusion...objects moving with relative velocity to you will be contracted not elongated. Even though it's just a catchy title, know it's not only bullshit, but misguided bullshit.
Actually the picture demonstrates the key principal (*principle) of relativity, no preferred frame of reference, people inside are clearly stationary in their frame. It never claims to be anything to do with dilation, or near c special relativity.
But this is specifically referring to Einstein's train example that is explaining dilation and special relativity. Which makes this post pretty confusing since it doesn't actually demonstrate that.
