In Ontario, Canada (and many other parts of the country, as well as many other countries), texting and driving is strictly illegal. In fact, any handheld device ("I wasn't texting officer, I was changing my music on my ipod") is also strictly illegal, and even though some people still do it, it has been reduced drastically.
Even talking on the phone with the phone in your hand is illegal. I remember when I was in FL and everyone is texting and driving, talking w the phone in their ears not looking at their mirrors, insanely dangerous for a rider (i used to ride a vmax there).
The USA needs to sanction a federal law on this regard, QUICK.
