Warming up too fast = hot fluids in a cold engine with cold seals which is not good. It's the same principle as keeping the rpm's low when starting out. The cooling system in a car is sufficient to warm it up when you start out. Only disadvantage to warming up is that a cold engine burns more fuel (wasteful and worse for the environment.) Even when warming up you want to take it easy when starting out because your tranmission fluids also need to warm up while driving. I'm not saying to let the car sit for 10+ minutes but 2 minutes or so (especially when cold out) is good for your car. Older cars benefit more but the principle remains the same.

Well, it better be. But what is so important about driving faster than anyone else? Lots of people go through life doing things badly. Racing's important to men who do it well. When you're racing, it's life. Anything that happens before or after is just waiting.
