This is purely about emissions. Those experts don’t care about the wear and tear on your vehicle - they have an emissions agenda and the quicker your car gets on the road and out of hi rev/warm up in your driveway where it is pushing out the most pollutants through cold cats - is what they want. I just figure all the Prius/appliance drivers can listen to those experts and I will warm my vehicles up appropriately as needed.ever understood the car 'experts' that say 'don't warmup your car' just start and go after 2 minutes. There's no way an automatic tranny /torque converter is 'happy' about that. I KNOW my forklift loves a good 10-15 minute warmup before being asked to move !
