It's hyper super duper useful in rough climates. Primarily when it's minus 40 outside and you have kids, it's nice to warm up the car slightly before entering it. If you get spoiled, you might then also remote start it when it's plus 40 outside and you want ac to at least start.
Also note that "if it's left in gear" is virtually irrelevant in North America, fwiw - something like under 2 percent of cars here are manual. Vast majority of vehicles and models do not have it as an option.
Here it's cold in the winter and it is definitely illegal to install a remote start system in a car with a manual transmission.
Before my life in tech I worked in car audio installs back in the 90s.
One day one of the senior installer techs put a remote start in his own Mazda truck which had a manual transmission. A bit of time went by and we were outside smoking one day when he must have hit the button in this pocket. Apparently the e-brake wasn't on, and the truck was in first gear, so it started and drove across the parking lot and hit the wall of a building as we all watched.
IIRC he just bypassed the sensor that would have been for Park on an automatic, since there were no manual transmission kits for sale as they were (and I think still are) illegal for sale where I live.
He would even refuse to do this sort of thing for other people so it was pretty funny it happened to him.
Thanks also, I get it now. I used to do this manually sometimes in the Netherlands to warm up the ice to make it easier to scrape off. But it involved the spare key to relock it while running and also to set the heat to full blast. We never get minus 40 though and where I live now it doesn't even freeze :)
And as we also have pretty tiny engines here, it takes a long time to heat up this way because first the cooling water needs to get warm which takes ages with the engine running stationary. So I only did this once in a while if it was really needed.
My old Volvo did have an option to open all the windows with the remote though which was great to let the heat out in summer.
Note that, for emmesions, heating up the car in stationary is actually positive. It prevents driving a car with a cold engine. Cold engines cause horrible inefficiency in cars. It's one of the reasons why city driving is worse for mileage and emissions than highway driving. Shorter trips.
Seems to be caused by the period before the catalytic converter gets up to normal exhaust temperature.
“Vehicles fitted with catalytic converters emit most of their total pollution during the first five minutes of engine operation; for example, before the catalytic converter has warmed up sufficiently to be fully effective.”
Sure. But otoh the car is idling for tens of minutes maybe and possibly no single part of the engine and exhaust system is gaining the needed temperatures to operate cleanly. This means more emissions, more wear and more stressed out neighbours. I'm sure about the last one at least.
Almost every car I’ve recently owned and/or rented has this option: unlock the car, then hold down the unlock button to roll all the windows down (and in some models, additionally open the sunroof).
I hate this feature with all my heart. Ive never needed it or wanted it and can easily roll down my own windows. 4-5 times ive come back to my car and windows rolled down after shopping or working as i must have accidentally activated it.
I hate it when it's operated by remote, but it's really nice to do it with the key in the lock. If you have to leave your car outside in the sun and you know it won't be raining, you can easily crack all the windows 1.5 inches or so to let the heat easily escape your car.
I didn't realize the percentage of manual transmissions was so low, no wonder the car culture there seems to idolize it.
In my climate, on a 45c day, inside the car's going to be more than that. It's definitely a workout for the generally imported car's A/C unit. I am guilty of turning the car on and waiting under a tree or something for the AC to bring the temperature down to at least ambient.
I'm looking at a series hybrid car. I must admit, pre-conditioning the car off the battery would be pretty luxurious.
Spoiled? Being low tolerant to anything above 23C I find getting into these pressure cookers a very uncomfortable experience. I’m simply refusing to get a taxi when such happy summer driver arrives with windows down in 35C+. I’d better get into an ice cold car rather than that.
I live in a country where it's above 23 degrees most of the year :) I got used to it. When I first got here I used to wear T-Shirts in winter at the agony of my colleagues. But the second year was a lot tougher..
