This is why God invented bedrooms

And showers. And hastily-cleared dining room tables. And basically anywhere other than carbon monoxide-filled garages as ideal settings for sex:

"A man and a woman retreated to their Volkswagen to have sex... Most likely the lovers turned on the engine to get warm," Interfax reported, citing a source in the Moscow police force. During a moment of "intimate closeness," the pair, in southern Moscow, inhaled the gas and died, the source added.

Well, at least they died doing what they loved. Inhaling noxious fumes.
