Recent word from the AAA Foundation for Traffic Safety explains that drivers using advanced safety systems such as cruise control, lane-keeping, and automatic braking are nearly twice as likely to be distracted as those driving less-equipped cars. This should remind us that human beings are not as predictable as we like to believe.

We humans think. We adapt to new circumstances and respond to incentives. And that means efforts to reduce risk by regulation must take account of how the human mind can respond to an otherwise safer environment.
