It is true that the CAT must get up to temperature before it operates at its best. But I partially agree with you. I've often wished that the truck would let me run off of battery until I requested enough power to start the engine the first time. Once that happened I see no problem with how it acts now.

This would measurably increase my mileage as well. Certainly going starting up, going down my driveway, and sitting at my first stop light could all be done without the engine. The distance isn't tremendously far, but the time I spend there not moving with the engine running seems like a waste.
