If you sleep in your car are you supposed to crack open a window?

@NeoNeo I know this is a dumb question but even if it’s heat?

@DeluxedEdition Oh if its a hot day then yes its wise to keep it open unless you're sleeping with car and ac on. In that case car shouldn't be in confined place

@NeoNeo mostly it’s not in a confined place. Usually I’m sleeping in my car parked outside

Thank you :)
