Anyway, we don't want this getting into another speed discussion so let's get back on track.
"I'm on the A40, it's dry and clear, good visibility with light traffic..... I'll probably be about an hour and a half unless the traffic worsens. There appears to be a queue ahead, better make that two hours"
"We're on an A road, dry, clear, traffic flowing, red car coming up behind is moving to outside lane. Looks like a queue ahead, ease off the throttle to reduce closing speed; this might slow the journey somewhat."
One said on a mobile 'phone and the other to an (imaginary?) companion. Which is decreasing the driver's concentration?
The first one.
A couple of points:
-When using a handsfree system there's so much "lag" and the quality is so poor that it requires exponentially more processing power to be diverted to the act of listening than, say, talking to a passenger in the car.
-Talking on the phone is nothing like doing a commentary, at least not a kind of commentary I'm familiar with!
