One of the biggest assaults (and insults) against the Prius, going back a long time, was that it was too complicated and the systems were too delicate to be robust. The critics said, without good reason, that the Prius could not hold up under hard, commercial use. And yet, it's now the darling of cab fleets all over the world. Prius cab have logged millions of miles with lower maintenance and fuel costs than every other car.
It's nice to see those critics silenced.
