Stop making fun of me, its actually hilarious though, since no one got injured. I was actually cleaning my car in the backyard one day and I guess i might have accidently left it in gear and then i remote started it from my room and when i looked out the window about 5 minutes after i didn't see it in my back yard. went like a frantic lunatic looking in the front of the house didn't see it, looked out the 1st floor window didn't see it. I threw on my boots and......there it is, stopped against my neighbors house. that explains my left front fender.
Then the time to the post office, left the car in gear (lazy to pull the hand brake) and then i forgot that i left it in gear while I was double parked and bam the car drives it self into the side some astro van's rear bumper. no damage to his, but damage to my right front fender.
Well let me stop embarassing myself.

THey are working and doing nothing, so they are just wearing down while no motion is going on.

idling for long periods of time is no good for engine..
just start the damn thing..
put on your 5 pt harness
and adjust ur hair..
after that you can drive easily..
under 2500
and then when u see ur temp and idle are normal just drive like u would any other time..

It's really the opposite, think about it. When you drive your car with a cold cat it'll clog it more than if it were idling because the engine is putting out more exhaust.

Aggressive racing has the idea, and after you do all of that especially the hair, you will be at 30 secs and then after the car is warm while driving then you can grip it and rip it

Really guys... if driving a cold engine is so good then why does every BMW M-series car have an adjustable redline and rev limiter depending on the temperature of the engine? If you read ANY automotive book or take automotive classes they will tell you everything I have.

no one said driving a cold engine is a good thing is just that the engine does not need to be warmed up properly and not just left in idle.
check this out some quotes from sites:
"Give the engine at least 30 seconds (longer if it has sat for more than 24 hours) before popping it in gear and roaring off."
"You don't have to let the engine run on and on before driving away. About a minute is all that's needed to sufficiently warm up the engine. "
These are just a few quotes from sites.
And BMW has different shift points in the M3 due to gears, not coldness of the engine. First gear redline is quicker than the rest.
