There is a ban on using cellphones, MP3 players, GPS, and other such devices while driving that takes effect today. At a fine of $155 Canadian, this could be a somewhat expensive use of a device that you can possibly make.
Frankly, it's about time this ban came into effect, as too many folks driving out there are just sloppy drivers because of their use of cell phones, MP3 players, and the like in their cars. Should be an interesting week on the roads. :)
