A study by the Department of Psychiatry at McGill University in Montreal concluded that the habitual use of GPS navigation directions on a smartphone impairs a person’s ability to deal with spatial relationships.
I personally think this trade is worthwhile.
For example, last Saturday morning I had to drive from my home on Three Mile Harbor Road in East Hampton to my dentist at 39 County Road in Southampton. My brain told me that the easiest way would be to follow the Montauk Highway 16 miles to the County Road 39 turnoff, then up 2.3 miles where my dentist is on the left. However, traffic can back up for miles on the Montauk Highway. My GPS was much faster.
I turned left out of my driveway and went 1.2 miles right onto Tub Orsman Road. Then 0.1 mile right onto Bow Orsman Road, a 2 minute link for 500 feet left onto Bothers Lane North, then 0.2 mile left onto Central Highway then quickly onto Wooded Oak Lane On the right, right down Creek Road for 0.1 miles, then left for 0.6 miles on Old Orchard Lane after a 5 minute stop, for 19 minutes stop for 2.1 miles on Cedar Street, then left on Stephen Hands Path, then, due to a 22 minute closure due to a tree service truck, right on Two Holes Water Road for 3.6 miles, then left on Swamp Road for 6.7 miles on Sag Harbor Turnpike Turnpike Turnpike Turnpike Turnpike Turnpike, then left on Hampton Street for 2.8 miles, then straight after a 31 minute link on Ferry Road for 1.4 miles, then left on Short Beach Road, after 0.3 miles turn right on Noyak Road for 2.1 miles. Turn onto Long Beach Road.
Continuing on Noyak Road for 3.8 miles I turned left onto Deerfield Road for 2.8 miles then right onto Todd Road for 0.3 miles at the edge of Woods Road for 1.6 miles to Majors Path where there was a 32-minute draw. -up, and then right on Great Hill Road, right on Majors Path 2.4 miles, then after a 55 minute stop for 0.7 miles on Seven Ponds Road for 2.1 miles, then one on Lower Seven Ponds Road and continuing right, go 1.2 miles onto Pond Road, turn left, then onto Narrow Lane for 0.3 miles, onto Scuttle Hole Road, then onto Montauk Highway, turn right onto Rose Hill Road for 500 feet, which is then David for 0.2 miles. Becomes a lane. An 8 minute stop, a left side on Montauk Highway, a right side on Old Mill Road and a 16 minute stop for 0.9 miles, left in a 17 minute stop at 800 feet on Upper Seven Ponds Road . Intersection with Mecox Road then 800ft further left on Seven Ponds Road where there was an initial 6 minute link after 0.2 miles, then left onto David White Lane for 0.2 miles, left onto the bypass side County Road 39 and then 0.1 mile after that was my destination on the right.
Elapsed time: 5 hours 9 minutes.
If I had taken the Montauk Highway route, it would have taken 17 hours and 14 minutes according to the GPS. It was quite a saving.
Conclusion: GPS guidance is worth it, addiction be damned.
