I'm apparently not a Coco Mat candidate.
I've dumped at least 3 full Circle-K Polar Pops of Diet Dr. Chemical (tastes more like real Dr. Chemical) in the front of my car and a half-dozen more in the front of my current work van. Jeanie will not allow me liquids in the minivan. I sip Diet Dr. Chemical from a hop-flask when I'm driving the limo, just because.
Anyhow, the last time I capsized the Titanic in the speedster (... um, last week) - I pulled over to the side and sopped up what was rolling around in the footwell with the tee-shirt I was wearing. I put it back on and proceeded on my way. It looked like hillbilly tie-dye, but what do I care? The roll of duct-tape cup holder is useful, but no match for the super-cup from the Circle-K. It's more a 12 oz affair.
Aspartame is purported to be really bad for me - but it's not sticky, and its lack of sticktoitiveness has saved my bacon at least a hundred times when I've spilled a bucketful of something all over something else.
