The question is what the automakers will do with the information gathered by those sensors, and we've seen some fairly novel innovations. This latest solution from Lexus may not be the most useful, but it's definitely one of the most interesting we've seen to date.
The Japanese luxury automaker's Australian division cooked up this special RC F show car with a heart-rate monitor and a special electroluminescent paint job. The sensors detect how fast the driver's heart is beating, and displays it accordingly down the side of the car's flanks. In daylight it looks like it's painted plain old ordinary silver, and otherwise it's the same luxury muscle coupe we know, with a 5.0-liter V8 churning out 467 horsepower in resolute defiance of the downsizing/turbocharging trend that's sweeping the industry.
The project was cooked up by creative agency M&C Saatchi and uses glow-in-the-dark paint from American specialist Lumilor. Is it pointless? Almost entirely. Does that make it any less cool? Of course not.
