Ahh this brings up some good technical questions.
First of all isnt a GPS an wireless communication device capable of sending data. A blackberry does that to? Whats the difference. Both are distracting.
Oh wait but what if i decide to use a GPS program on my blackberry.
The built in one is safe but the phone one is not?
I thought all this was dangerous. But it also excludes tracking systems?
Can someone explain to me what training or qualifications UPS drivers or truckers have that would allow them to use such a device while operating a vehicle?
This would qualify.
Technically i could touch a 407 transponder as well while entering the highway to and be charged as this device that transmits data.
What if i dont have an in car GPS and need to use google maps to find my way?
Maybe ill pull over and twitter Dalton McGuinty to find my way. 
Wait a screen visible to the driver.
So what if you had a son in the car who was playing a game boy, PSP, or watching a video.
Would this now be illegal as this would be visible to you.
Maybe tinted windows will be a good option for some people.
Besides if you got pulled over on the 401, what is stopping you from saying you were about to dial *OPP to report a dangerous driver or something you saw on the highway?
Man this legislation is confusing.
Bookm, ya i agree about insurance rates. I don't buy it either.
I wish insurance was not the law. Or people had more choice in selecting coverage without others ruling and mandating minimum this X minimum that Z, etc. I honestly wonder how much insurance rates would be in a truely "free market system" in which drivers had more control over what they wanted, and where insurance was not the law or forced to have. Maybee those drivers that have such a bad record that pay high premiums would not be able to afford insurance, therefore drive alot more careful as they don't want to be in an accident without it?
I think insurance gives people a false sense of security.
Anyways back to this i think people will do what they can get away with as always. For example you could just put the phone on speaker and rest it in your lap. Or at night you could turn off the screen, and back light on the keyboard, or just get tinted windows.
Hands free, or hands on. What is the difference.
Why don't we also make a law requiring two hands on the wheel at the same time. By allowing hands free this doesn't address the fact people are not paying attention.
