Furthermore this argument would favor plug-in hybrids, not fully electric cars.
If only 30 miles is required most of the times, why go with these big, heavy, expensive batteries when you need only a quarter of it. Something like the Chevrolet Volt would be perfect, fully covering the 93% case with its smaller battery, but for the remaining 7%, the gas engine gives it a better range than any fully electric car.
And for emissions, we are 93% there with a plug-in hybrid, so clearly that's the solution.
Except, maybe not... because there is another trick in that stat. Maybe 93% of the trips are less than 30 miles, but 93% of the miles driven are necessarily part of a trip that is more than 30 miles. Same thing for that "40 miles a day", it doesn't account for days where no driving happens. So it means that it you take a random car on the road, there is a good chance it is doing a longer trip than 30-40 miles.
