Read the picture choice by choice and it reveals a careful piece of engineering. The composition is a tight crop pushed close to the skin, cutting away everything but the face, the raised arm, and the arc of the wheel, so there is no room for context and no escape from the smile. The grin becomes the single dominant event of the frame, enormous and unavoidable, and the eye is pulled straight to it before it can wander.
The lighting is theatrical and split between two temperatures. Warm gold falls across her cheekbone and skin, while cool blue creeps along the rim of the steering wheel and into the shadowed edges, setting a living, illuminated face against a background of near-black. That near-black is functional negative space: it swallows detail so the illuminated face reads like a scene lit for film, a moment half-remembered from a movie.
Color does the tying work. The red of the lipstick is answered exactly by the red-painted nail lifted near her mouth, a small rhyme that makes the lower half of the picture cohere. Against the otherwise blue-and-gray tonality of the sleeve, that red is what jumps forward and marks the figure out as the focal point.
Then the typography. Across the top, in clean sans-serif capitals, the band's name spans the full width of the sleeve: THE CARS. The letters C, A, R, S are picked out in a brighter blue than the surrounding characters, a quiet typographic trick that makes the word "CARS" leap out of the phrase. The single translucent curve of the wheel completes the pun, because the image plays on the word without ever showing a car. There is no vehicle, only a steering wheel and the driver's ecstatic face, and the two together do all the suggesting.
What the whole image means follows from that sleight of hand. It sells motion, glamour, and exhilaration through a portrait of pure pleasure rather than any machine. The tight crop and the split warm-cold light turn a smiling model into a promise of speed and release. It is a portrait of exhilaration lit like cinema, and the reason it keeps you staring is the gap between the face's total abandon and the cold blue restraint of everything framing it.
