The ultimate cup holder guys have a page where they compare their product to a bunch of others, including the Rubber Queen. Some of the comments are kind of amusing.
Hrmm, yeah, I like those too.
I took a look at it when the link was shared and it is one that I considered when I was looking for one. I have a few friends that have similar (might be the very same one) and they all consider it acceptable. However, no one is truly happy with them. My particular problem is that I don't like cupholders on the door (or anywhere where they may 'get in my way' or otherwise consume my immediate personal space). The Ultimate, on the other hand, sits on the floor, under your knee/thigh. You do have to reach for your drink but when not drinking it is definitely out of the way. It is also out of sight which makes the interior look cleaner.
why would you do that?! you should be going down through the gears taking advantage of engine braking and keeping those revs high for the exit
Because you're just maintaining speed on the highway, as opposed to stopping then accelerating back up to speed, repeatedly. Highway cruising at *ahem* legal speed will always give better gas mileage numbers unless you're in a hybrid which recovers energy from braking.
