More DUH!

From a spam notice: "Now you can talk and drive without using your hands."

No info on how the Bluetooth drives for you.

I am struck by how late to the dance are legislators, etc. who pretend that they are just finding out that distraction is the danger, not just using one's hands or eyes.

Particularly with aging I notice that just distractive thought is dangerous as are tuning the radio, looking at your passenger, and a host of other activities, but what we are getting are rules against texting and in some cases using the cellphone while at the wheel.

They have in some places forbade putting a TV where the driver might watch, but the GPS has eased this ban on visual distraction, although one could use the navigator in voice-only mode, but it doesn't work all that well.

Just as we made progress with seat belts and drinking/driving we will have to address distraction per se. The SKI Study on elder vision includes: "aging significantly reduces the effective visual field under conditions of divided attention (white circles, red line), and coarse stereopsis (depth perception) is also greatly impaired." and "Older persons self-restrict their driving based on several aspects of their vision, but not on the basis of deficits on attentional fields (measuring divided attention performance — one of the most important correlates of accidents). Testing and education is therefore needed."

And all Department of Motor Vehicle testing agencies still use the primitive visual acuity charts that are actually pretty useless.
