Almost nothing (keyword: almost) on the road pisses me off more than drivers talking on the phone. There's now a push for a ban on cellphone use among commercial drivers, as reported by the Times. What's taking so long for this push to become law already?
This reminds me of something on my to-do list: write the National Association of Broadcasters to reach out to traffic reporters, on tv and radio, to consistently and continuously tell drivers to put away their phones and just drive, because people are dumb. Stupidity does not deserve civility. (...feel free to join my effort :) )
