Will it get in the way when driving? No. As far as the small bottoms large top drinks, my friend is going to take pics and video's of it installed on his car, with large drinks in it. I don't drink those fountain drinks much. When I get the pics, I will post them. He will be posting a review of the product as well.
Yeah, no slamming the door with open drinks. But usually, most people that drive around have their drinks in hand when they leave the car. A lot of cars have cup holders in their door as well. Same rule applies to them.
You can install the cup holders any where you would like. I put it on the door because it seemed to make the most sense.
Here's another place it can be installed (sorry for the dirty interior. it's a mock up car lol)
