Please settle this discussion about cars between my husband and I!

I do neither. I start my car up and go. Its illegal here as well. Its a nice hefty $300 fine if caught. I am not chancing that.

Actually in new cars,warming it up is just for your comfort inside the vehicle

not only wastes gas but if you leave your car on while waiting inside the house , you could get sick from the fumes like the way my neighbor did once. She immediately stopped warming up her car that way, and her health issues slowly went away...

I always warm up the car for about 5-10 minutes. But that's so I'm not freezing my tits off.

We get -20 and below temps in the winter, I do NOT drive it in that kind of weather without warming it up at least 10min, usually a little longer... It is illegal here too but i've never gotten ticketed or know anyone who has honestly, even the cops in our town do it! Now if its only a little bit cold in the morning (like below 15 degrees) I think a 5min warm up is probably enough. I've been starting ours at about 7:05 every morning and I take the girls to school around 7:15, or as soon as we're ready. It was 10degrees out this morning and lots of ice but I probably didn't need to let it run that long...

Idk..our cars are always inside the garage, so warming up isn't necessary.

I've heard it is not good to start your car and leave it running just to warm it up...but that doesn't stop me. If it is cold outside, I always start it up 5 minutes before leaving for the bus stop for my daughter because I hate sitting there doing nothing in a cold car, but just to drive to town or something, I never warm it up first.

We park the cars in our attached garage, but I just open the garage door before starting. Never have felt any effects from fumes that way.

I will warm up the car for a couple of minutes if at all, but then again I live in a tropical climate place, but doing it the way your husbands does it seems to me like he is wasting a lot of gas and time in the process...

I never let it "'warm up". I just start it and go. Of course, we also don't usually get as cold as it gets up north - lower 20s, usually at most. I might sit there for a minute or two to wait on the heat, but that's about it.
