If you haven't noticed, a convergence between automotive technology and consumer electronics is taking place. Everything is Bluetooth this and iPod that, but you get the drift. Forbes decided to list some their top gadget picks. Most of the gadgets listed are add-on, or in development, but it won't be too long before they show up on the options list of your favorite automobile. Among the coolest technological enhancements listed is the radar sensor system developed by Valeo Raytheon, the partnership of the defense giant Raytheon and car parts supplier Valeo. The system, called the Personal Driving Assistant, uses radar sensors to detect vehicles in a car's blind spots and alerts the driver with icons in the rear view mirrors and a warning tone. This perfect option for those drivers who refuse to turn around before making lane changes could potentially show up in vehicles next year.
