I think it's a real stretch to call this a safety issue to the degree that an official report needs to be made about it.
While the existing Air cup holders are a tad tight , they are perfectly capable of fitting 12oz cans, 20oz bottles and a large variety of cup sizes without spilling.
But then what happens when they make the cup holders bigger? Suddenly common cup sizes that previously fit securely are now loose and tip over when you accelerate and turn, once again potentially spilling hot liquid on your lap.
I KNOW this is going to happen because I have frequently driven other cars with different sized cup holders and every single one of them had sizes of drinks that would not stay securely.
So what then? Another new official safety complaint because now smaller cups don't stay securely and might burn someone?
You literally cannot design a perfectly sized cup holder. it's just not physically possible.
So yeah, in my mind making this an official safety complaint isn't really valid, unless your end goal is a complete ban on cup holders in automobiles because it's impossible to design one that will perfectly and securely fit any cup that some yutz wants to use for their scaffolding hot coffee.
If you want your coffee with you, buy a cup that fits in your car and has a secure lid. Failure to do so puts the blame for any spills directly in your lap. (Pun intended)
