Cellphones can disable Nissans - Los Angeles Times: "Nissan North America has a warning for customers: Placing your electronic key too close to your cellphone could leave you stranded.
The automaker is asking customers driving new models of two of its flagship sedans to keep their car keys and cellphones at least an inch apart to avoid disabling the 'intelligent keys.' "
I think Nissan is off to a good start but they need to do more. Perhaps they could get the steering wheel to burst into flame if a cellular phone is used by the driver while the vehicle is moving. That would be good.
