You should look into being more courteous to those who choose to travel with coffee.
Roads: You should become more smooth. My full coffee cup (and also me) do not appreciate your bumps, dips, pot holes, and general rebelious nature. I do not enjoy holding the coffee cup the entire time I am driving to save myself a mess that could potentially happen because of your rough nature.
Cup Holders: I do not even know where to begin with you. You need to be more like a transformer. You should be able to transform to any size cup I desire to place in you. Just as with roads, I do not enjoy holding my cup of coffee because I am afraid it will tip over because you are not well suited to hold that cup.
Now, please both of you, go and make the appropriate changes I have suggested. I would appreciate that greatly.
