Isla, I think one reason women drive minivans because men also have a hand in the decision-making process - and if they ever need to use the "family car" they don't want to have to drive a <shudder> minivan.
Seriously, though, even though minivans are in fact more practical, SUVs look better, typically have better performance (depending on the model), and can be cheaper in some instances. Also, there is a TON of selection and competition right now in the SUV market - they are aggressively marketed and people can find just about any combination of price/size/utility etc. to meet their needs. BTW, I don't drive an SUV, this is just my theory.
And yes, you are a nerd, but not because of the minivan.
