Why are my car windows like magnifying lenses ?

Hi
I set my car windows IOR to 1.4 like glass supposed to be but It creates a very distorted refraction that real car windows do not have. I can only fix it by setting IOR to 1 but then it looks like glass window is missing. Any ideas
Thank you

It's possible that your windows have no thickness, so it's rendering as though it's one big solid piece of glass.

I don't use Max but in Cinema 4D I just extrude the single planes to give it some thickness and this solves the problem.
