Most people have experienced the Doppler shift and sound waves, but humans dont have direct experience with the Doppler shift and light waves. Why? The human nervous system is not sensitive enough to detect the doppler shift in light waves Only light from stars is subject to the Doppler shift. Earth's atmosphere blocks the Doppler shift. The Doppler shift is too large for humans to perceive.
