Because it doesn’t matter. Fuel consumption is perhaps 10% or less of my cost per km. If that fuel consumption goes up or down 10% that means my driving cost goes up or down 1%. My 60L tank takes me 1100km. I don’t care if more streamlining or lower height would take it 1200km. 1100km is at least two toilet breaks anyway. So I’ll pick the practical car I want/need and don’t care too much about consumption so long as it’s reasonable. I wanted a bit higher clearance and 4WD (and I use it too - but rarely). Last time around it was a jacked up wagon and I don’t think I’ll buy an SUV because the 4WD wagon is so much better at everything plus it’s cheaper.

With an EV, this equation of cost and range goes out the window. The difference between 300km and 400km range is huge.
