Driving to work my car when “BEEP BEEP BEEP” the dash starts flashing after a few second I realise this over the top warning is to tell me its 3 degrees out side. I know its cold out . I walked from the gaff to the car. What possible use is warning? And why 3 degrees? So if I drive into a bit of sun and it rises to 4 and then into shade and it drops to 3 is it going to warn me like engine id about to leap out of the bonnet? The only use I have ever seen for car thermometers at that when people arrive to work they can say “ohh its cold this morning, my car said it was 3 degrees” so it’s a small talk generator for people in offices
