Glass-holder for car

Hello everyone! 

I've a car (lada kalina the 1-st generation), unfortunatelly, it hasn't a glassholder. Every time when I buy a cup of coffee or tea, I don't know where I can put it. It making nurvous when you drive. Agree?   

That's why I designed this glassholder for car, it really holds any 2 cups which volume from 200ml to 350ml. (You can see that on attached photos).  

This glass holder was created for cars, which hasn't it.
