Bluetooth is cited as the communication protocos and requires power. Once the battery runs out - bingo. I'm talking.
Plus great point about the key fob. I drive a cheap mitsubishi galant and even it has a keyfob that incorporates a door and trunk features. cant see slipping this device over anything but a old ford or chevy key.
While I completely agree with the intent of equipment I think I see some problems.
1. This will not block a passengers phone, or a disposable cell phone.
2. Both of my current cars have 'chips' in the key for security purposes. These cost around $100 to have replaced. How can the developers state their fobs will be $50? Maybe for a dumb key system, but many newer cars have the security features that will interfere with or be impossible to duplicate.
3. Does this fob have a battery? If so, what happens if the battery is dead or removed, no signal, the cell phone would have no idea the car is being driven.
4. I won't even get into the newest keyless start cars.
5. Spare keys will not be covered, so it appears the easiest way around this system will be to go to the local hardware sore and have a 'spare' key made.
Once again, we are passing laws or installing equipment to force common sense. I believe that a much more effective plan would be to have the insurance companies change the policies around. If a cell phone was being used during an accident, the deductible goes from $500 to say $5000 or $10000. If you are ticketed with using a cell phone while driving, your rates just went up 10% 15% or more. people respond to things that cost them money and ignore laws and rules. I am sure that the teens will find ways around these devices, and 'you tube' will have the full instructions the next day.
I would rather direct funding toward developing autonomous vehicles. Then I can talk and text all I want as my car drives itself. As I commute 45 miles each way to work, I can't wait for my car to drive itself! But in the meantime, maybe these guys can save me from the teenage girl texting in her Cadillac Escalade monster SUV as she blows past me at 85 MPH.
