NHTSA Complaint #11413277 — 2020 TESLA MODEL 3

LIGHT SOURCES SUCH AS TAIL LIGHTS OF OTHER VEHICLES, TRAFFIC LIGHTS, AND LIT SIGNS, ALL HAVE AN ARTIFACT EFFECT - VIEW OF THE LIGHT SOURCE HAS A DOUBLE THAT EXISTS RIGHT ABOVE THE ORIGINAL SOURCE WITH A SLIGHTLY DIMMER BRIGHTNESS WHEN VIEWED THROUGH THE WINDSHIELD. THIS IS NOT AN EFFECT CAUSED BY POOR EYESIGHT, THINGS LOOK NORMAL WHEN VIEWED DIRECTLY THROUGH AN OPEN WINDOW. THE EFFECT CAN BE REPRODUCED AT ANY TIME, BUT IT IS MOST NOTICEABLE AT NIGHT WHEN THE VIEW OF THE ARTIFACT IS IN HIGH CONTRAST TO DARK BACKGROUNDS. THIS EFFECT IS MOST NOTICEABLE ON LED LIGHT SOURCES, SUCH AS LED TAIL LIGHTS. THIS EFFECT IS PRODUCED REGARDLESS OF THE STATE OF THE VEHICLE - OCCURS WHEN THE VEHICLE IS STATIONARY OR IN MOTION. THIS IS A SAFETY CONCERN AS DOUBLE VISION - SEEING ARTIFACTS ON LIGHT SOURCES THROUGH THE WINDSHIELD CAN CAUSE EXCESSIVE STRAIN ON DRIVERS' EYES, AND CAN BE AN UNWELCOME DISTRACTION TO THE DRIVER. THIS CAN ALSO POTENTIALLY CAUSE CONFUSION IN THE DRIVER WHERE THE LOCATION OF A LIT OBJECT MAY BE MISJUDGED BY THE DRIVER WHO SEES ARTIFACTS ON THOSE LIGHT SOURCES.
