Despite the public shame of driving around with a cell phone jammed against your face and the growing number of laws against it, people just can’t stop dialing and driving, it seems. Could the next step be technology that actually disables your cell phone while you’re on the road? A Canadian outfit called Aegis Mobility proffers this new system, called DriveAssist (not "DriveAssistT," a typo which is widely being re-reported), which stops calls while your car is in motion. It doesn’t block calls through any sort of electromagnetic shielding or jamming system, it’s actually considerably simpler: When your car is moving, the system simply tells your wireless carrier to hold incoming calls and texts and blocks outgoing messages as well. When you stop, the calls come through normally. The advantage to such a system vs. a crude jammer is that your caller receives a notice that you’re on the road and unable to receive calls, rather than just going to voice mail automatically. Reportedly they can also bypass the restriction by pressing a button to go into "emergency mode" (which I’m sure would never, ever, be abused). The software will work with Windows Mobile and Symbian phones, at least to start.
