If you want to know what might be available the next time you purchase a car, (or more likely the time after that), the September issue of Popular Science is devoted to "The Future of the Car". It doesn't look like the flying car will be around anytime soon and Popular Science pokes fun at their own misguided July 1959 cover story proclaiming the Hovercraft as the wave of the future.
What is coming? Possibly the Toyota Volta, the modish hybrid concept car. Also pod cars that drive themselves, sensors that shake you awake if you nod off, and wireless radio communicators that will let the abuse you hurl at nearby drivers actually be heard.
Most exciting of all? Black ice detectors. My sister is so obsessed with black ice that any time the temperature dips close to freezing I get a call from her in ominous voice, telling me that the roads are covered in black ice, nowhere is safe, everyone should stay home, the enemy is upon us.
Popular Science is available in digital form, both as an annual subscription and single issue at Zinio (September doesn't seem to be available yet, but probably in the next day or two.)
