soda isn't good for you, anyway...
my solution is, i removed the passenger's seat. like, hoo needs passengers, anyhoo? they're always yapping... hey, go that way... look out... be careful... slow down... you almost hit that car... how many times have i told the dern fools that almost only counts in horseshoes, and atomic bombs?
now i have this neat little... "rack" over there. it holds sodas, even sandwiches. it also has shelves that hold a fair selection of weapons, for those freeway drivers that just have to be... "difficult," or don't know how to let the clutch out... i keep a few laws rockets, for them

and a few grenades, for those pesky tail gaters.
KA-BOOM! sssssse you later, my son... work great for nosy cops, too. just pull the pin, hold 'em for 56 seconds, then gently toss 'em out the moon roof...
although my passengers (if any) are obliged to ride in the back and despite the uptick in the cost of driving, since i built my little rack i find i usually arrive at my destination, smiling
