In Minority Report, the Steven Spielberg thriller that opens June 21, Tom Cruise plays a police detective who bombs around Washington, D.C., in a red clamshell-shaped Lexus, tracking down future criminals. The year is 2054, and Precrime, a psychic technology that enables "previsualization," makes it possible to identify and punish killers before they strike. Precrime advocates promise a zero U.S. murder rate within six years. Now picture this: Someone's accused of murdering a person he hasn't yet met.
Solar panel roof. Solar panels have been used to power A/C in hot, parked cars.
Speed-sensitive ride-height adjustment on wheels, plus adaptive springing and damping. Similar technologies employed by BMW, Cadillac, and Mercedes today.
Satellite-based navigation and guidance. Widely available now.
Rear view via closed-circuit TV. Already available in the Infiniti Q45.
Personal computer with Internet link, customized music, news, stock quotes. OnStar system will soon offer most of these features.
Carbon-fiber-reinforced composite body repairs itself after damage. Self-healing composites are in development. Repair job probably won't look like Earl Scheib's best work anytime soon, however.
Fuel cell drives a 670-hp electric motor. Plausible, though breakthroughs in fuel cell or hydrogen storage are required. 670 hp beats that of an Indy car.
Laser-guided cruising. A precursor has been studied in California: Magnetic pins embedded in the road enable cars to cruise at highway speeds while driver writes film script.
Infrared system intervenes to prevent collisions with fixed or moving objects. Certainly possible, but likely a decade away.
Automatic valet system parks vehicle and returns it to owner via remote command. Conceivable. Would hacking yield an automatic theft system?
Controls responsive to voice and gestures. Jaguar and others offer voice recognition. But gestures? Don't give a driver the bird.
Body color changes to suit mood or attire. Distributing color within the composite is no problem; making it variable is not so simple; previsualizing a color to go with your mood and your clothes could be a nightmare.
DNA recognition security system. Remember Gattaca? Mighty costly anytime soon.

James Bond thwarts nuclear Armageddon, again, with a Lotus Esprit doubling as
a submarine. A submersible was outfitted with an Esprit's body panels for the stunt.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
