If people have returned to their normal driving habits (speeding over these 3d illusions) it means that at some level, they have reprogrammed their brains to ignore some 3d-like obstacles, because they may be fake. It works in case of the illusion, but I wonder if it would eventually impede their reaction time to other real, but similarly appearing obstacles.</text><parent_chain><item><author>malgorithms</author><text>There is an analogy here to the slippery-slope of attention-getting ads on the Internet.

On the day of the change, only 157 minor accidents were reported, of which only 32 involved personal injuries, with only a handful serious. On the Monday following Dagen H, there were 125 reported traffic accidents, compared to a range of 130 to 198 for previous Mondays, none of them fatal. Experts suggested that changing to driving on the right reduced accidents while overtaking, as people already drove left-hand drive vehicles, thereby having a better view of the road ahead; additionally, the change made a marked surge in perceived risk that exceeded the target level and thus was followed by very cautious behavior that caused a major decrease in road fatalities. Indeed, fatal car-to-car and car-to-pedestrian accidents dropped sharply as a result, and the number of motor insurance claims went down by 40%.&lt;p&gt;These initial improvements did not last, however. The number of motor insurance claims returned to &amp;#x27;normal&amp;#x27; over the next six weeks and, by 1969, the accident rates were back to the levels seen before the change.&amp;quot; &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;Dagen_H&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;Dagen_H&lt;/a&gt;</text><parent_chain><item><author>malgorithms</author><text>There is an analogy here to the slippery-slope of attention-getting ads on the Internet.
