Too cold for hand signals

After a year of hand signals –which no one under the age of 65 has ever seen– the Jeep has turn signals. I wasn’t looking forward to a winter of unzipping the canvas door on the Jeep to stick my arm out for a signal. Why drive the Jeep in the winter? Like the pickup (1977) and the Land Rover (1979) it needs to be driven regularly. If I drive a different vehicle every day, that means each of them gets some exercise twice a week.
