In general I agree, but lets do some napkin math:

UK 9.34 million hectares agriculture area. [1] 6,470 l/ha ethanol in Brazil [2]

60,4 billion liter ethanol for all agricultural land in the UK. (Surely a big share of the land is not good for this usage but what ever.)

About 45 billion liter of gasoline and diesel used in UK per year.[3]

I mean, it is not totally off by orders of magnitude to be practical for a significant share of driving.

Well, most of that land is already used to produce food. I'm not so sure whether it would be a good idea to start up serious competition to food production.
