This sounds like a remix of one of the many &quot;internet is making us dumb&quot; stories. If anything the existence of GPS, satellite, constantly updated maps, and now detailed 3D city maps makes our &quot;cognitive maps&quot; (whatever that means) far better now than in the past where our navigation was done from printed Rand McNally folding map.<p>The reality is there are a lot of impaired drivers on the road. May be they have been drinking, have early onset dementia, or just a mixture of prescription medications with undocumented side effects. A lot have spent half the time sending text messages on their phones. Whatever the circumstance, some of the tools we have now let them survive longer or at least pretend they know what they are doing.
