I must have gotten up on the wrong side of the bed this morning, so pardon the snark, but commercialize that? It's two $3 bicycle water bottle cages and a $5 piece of HDPE sheet. I guess if my coffee is leaking down the side a little bit the carpet can soak it up, so that's a feature. It's unclear how he has attached the little tangs on the bottom of the water bottle cages to the HDPE sheet, but HDPE is known for its tendency not to stick to anything and I don't see any mechanical fasteners so I'm worried about that part. The cages can be bent wider or squeezed narrower to accommodate any size cup until the cheap aluminum breaks at the welds. It'll take two hands to adjust. Who holds the coffee while you're adjusting it?
I think I'll drink my coffee first and then drive. Beverages have never been an integral part of driving a sports car for me anyway. I'll pop a water bottle and whatever I think I'll need into a small bag and toss it behind the seats. I can drink when I stop to pee.
As a side note, when I look inside cars in the parking lot what I usually see in cup holders is: loose change, sunglasses, wadded up tissues, janky old face masks, and cell phones. I rarely see a cup.
I think mister sourpuss needs a nap... I'll go do that now.
