It's getting colder in NYC, with crisp morning, and when I am outside, I constantly see people starting their cars, then as soon as they turn the key, they mash the gas, and start to rev in neutral like they are about to drag race, to warm up the car. WTF is wrong with people?

 

Cuz they're ignorant, that's all. If they knew it's not good for the cars, they wouldn't do it anymore.

 

Maybe they lease?

 

Or its a rental? Id definitely do that to a rental.

 

i've been in the car with people who do this .. to cars they actually own...

i cringe i've even said something to people a couple times..but eventually you gotta just give up and try to stay quiet...

 

Somebody has to keep the head gasket makers in business.

 

my ap2 started revving up in neutral. the dealer said it was to warm up the oil

 

it'll rev to something like 2k rpm to start... what the OP was talking about is much different and much more harmful.

 

Their cars, who cares, laugh at them and move on.

 

it was hitting over 5k on its own. pretty scary but only happened once.
