It's also helpful to idle for a few minutes if you are going to begin driving immediately at speeds in excess of 55mph. When I leave the seminary, the main road is a highway with a lot of traffic that is 55mph+. I tried driving once immediately after starting, and one cannot travel safely at high speeds while the engine is still cold. If I start and warm the car up for at least 5 minutes, it's much better. I love my remote starter.
