I can imagine the (legal) problems of having alcohol separate from the fuel. When it is mixed with petrol there is no fear that it will be used (or abused) "in other ways". When mixed with fuel alcohol isn't taxed as heavily: While a liter of petrol with 5% ethanol costs just under $2 here, pure alcohol at the liquor store goes for 7-9 times more.
Also, the law here states that "
It is illegal to have an open container with alcohol inside the vehicle". Imagine if the alcohol tube sprung a leak and the driver would be breathing the vapors for hours at a time. LOL
Now, legal nuances aside, having a second system paralleling the fuel supply would add complexity and weight (not to mention cost), but may be worth a shot (pun intended).
