Do you warm up or truck or car before moving in cold weather or even in warm weather?

I don't, start it up, keep track of the day before mileage and be on my way. Use it easy until it warms up.

I do, because I like a warm vehicle and clear windows. As far as your drivetrain is concerned though, there's no need. Modern oils, engines, trannys, and axles can handle it just fine.

Nope, never have. It will be warm enough in a few.miles.

I let things circulate for 30 seconds to a minute. Keep rpms low and not get on it till it warms up.

I don't.
Of course my car sits in a heated garage.
But if It wasn't as long as the windows are clear I wouldn't let it warm up.
I don't drive like teenager so I don't feel that running slow and easy will hurt anything any more than just sitting and idling.

Only if the windows are iced over.

I see so many people at work head out early to start their vehicles. I don't get it.

Oil pressure is a lot higher when its cold. I worry about seals when the rpm climbs between gears. I cant help but think lubrication might be effected to. So i let mine warm up a bit. 50 cents worth of gas in the morning isn't a that big a deal to me.

yes always in winter !!!!!!

Yup.
Boat motors and snow machine too. Heck, I even let my chainsaws warm up a bit before throwing the coals to em.

Always.....state mechanic told me 30 yrs ago biggest mistake people make is to not warm engine up and not change oil and filter (he likes 2500-miles).followed his advise for many new vehicles.
