Those short trips really kill the milage on a car
Most of the driving we do is short-haul driving in town, mainly trips of 4 miles or less. This is very bad for our gas milage when compared to the EPA "52 mpg"; we average a little less than 40mph, because the Prius wastes a lot of gas heating up the engine block when we start out, and by the time the block has heated up we're done with the trip.
If not for car insurance rates, it would almost be worthwhile to buy or build an EV for our in-town trips and leave the prius in the hangar except for trips to the coast.
