There's the minor issue of cold cranking amps. If you leave your lights and radio and windshield wipers on and try to start your car on a cold (zero degree) day, you might find it won't start. Granted, then you just have to turn them off with the accessory switch and try again, but some people today don't seem to realize that's an issue.


most cars will dim the lights / turn off radio when you start them anyway to get the maximum amps from the battery to crank the engine

I think i saw it somewhere that if you turn off your headlight while the car is off, the power might overload something. Maybe that is another BS :D

i think i understand what your boyfriend means. If the car have a light sensor and auto-lights turns the lights on or off automatically when needed... he must be ****ed off when he hopes those smart auto-lights are turning on when it's dark, but no, because girlfriend put the switch in off :)


Guys are like that. I also like all my car settings to be the way i left, eheh

I vote for this explanation. It's not that he actually believes it's bad for the car--he's just irritated by an out-dated habit and tried to find an easy way to break it.

^ I think she should find the switch for her boyfriend and turn him off.

well, you should have the lights on the 'auto' setting... problems solved, everyone happy, love is made.

Nope you're not talking crap.


He is lying but i can understand him getting frustrated by it. There's absolutely no reason to turn off the light on a car with an auto lights mode. You just force the next person taking it to put the lights back in auto mode again for absolutely no reason. I really hate when someone takes my car and turn off the lights.


Well there is always unnecessary wear and tear so technically he's correct but it's most likely she's being annoying by tinkering with settings she shouldn't be touching because they are already in the correct mode

rather than argue with the car owner you should respect their (reasonable) rules when it comes to using their car or buy your own
