I'm not talking 64 oz drinks hahaah, I usually have a 32oz coffee or water or soda with me, I have an hour commute to work and a 45 minute commute to school. I take a lot of road trips too, so things like cupholders, armrest placement, radio layout, etc. are all things that would be bothersome if not set up well.
I've bought a 44 oz plastic cup before and it doesn't fit in my Taurus' drink holder. Neither does a paper 32 oz cup. The bases are too wide. A 32 oz plastic cup fits fine though, cause it has a slimmer bottom section.
After the one console I bought, where 5 drinks tipped over in under two weeks (some mine, some passengers), I've decided that cupholders are pretty important.
