The headlighting of the "S" is ok but an area of shortcoming, I feel, is lack of peripheral lighting during moderate speed cornering. By peripheral lighting I mean, lighting the area of the turn 1-2 seconds ahead of you. This lack of lighting is evident on city street driving, which may risk hitting the inside curb, but more problematic at open road speeds and possible quick steering corrections needed to prevent running out of the driving lane early or late in the turn. Both cases may leave most drivers feeling wary of the next time they want to enjoy moderate speed driving of this fine car at night. I come from many years of road racing and don't compete anymore, but still enjoy moderate driving speeds. I very much appreciate the great design and workmanship of the car. It's a delightful car which still speaks to me after 6000 miles. Thanks Mr. Tesla!
