It's the fuel economy thing, used to be that an engine lost 33% of it's energy to heat. now with the federally mandated pathetic millage requirements, there is simply less waste heat to use for creature comfort now. What I've seen is in the Wife's jeep, one second of driving is worth 60 seconds of idling warm-up wise (untested). I've installed the low-temp, rain-repellent washer fluid to save fuel by making the snow and ice much easier to scrape off and I'm thinking about putting in an electric heater to pre-warm the cabin in winter. I could easily see a lot of you guys installing, engine, block, transmission and differential heaters or using synthetics with extreme viscosity ranges to help with cold temp millage numbers.
