It’s the nagging fear that rests in the minds of all who plan a family summer getaway: What if it’s a total disaster? For many former children of the 1980s, that fear stems from memories of “National Lampoon’s Vacation.” The 1983 comedy stars Chevy Chase and Beverly D’Angelo as Clark and Ellen Griswold, an all-American suburban Chicago couple who take their kids on an ill-fated cross-country road trip to a California amusement park.

Yes, the movie is hilarious. But in retrospect, some of the hardships the Griswolds experience — a detour through a dangerous neighborhood, being stranded in a desert, Chevy Chase’s Members Only jacket — are genuinely horrifying enough to scare anyone planning a real-life road trip.

That got us wondering: In the GPS/cell phone/Google Maps era we live in now, is it possible for “Vacation”-style calamities to befall a modern-day trek down the holiday road?
