Yesterday, Ontario legislature passed a law banning the use hand-held devices like the iPhone or BlackBerry while driving (with exceptions for cases like headsets, etc.).
I got an iPhone as soon as it was available in Canada, and since then, it is very rare for me not to be using it while driving. But I agree with this law. Very soon after getting an iPhone I noticed a degradation in my driving, because I wasn’t concentrating on the road. I’ve had two instances in which the driver behind me honked, because I didn’t move when the traffic light turned green.
Going back to driving without using my iPhone will be like trying to kill a drug addiction, but I understand why it has to be done. Luckily the law probably won’t take affect until autumn, so I have some time to adjust.
