That's only true because of the high gas prices over the past few years. With Tesla owners, car trips are favoured due to the low cost of fuel, the convenience of using your own car, the fun of driving a Tesla vs. the cattle car conditions of commercial airplanes, the inconvenience, expense, and safety issues of renting a car, and the anti-terrorism tactics at the airport.
Believe it or not, it is almost quicker to travel from Dallas Love Field to Austin via a Tesla MS than flying (about 190 miles).
Some of the less traveled cities (Tyler, Palestine, Fredricksburg), it takes less time because it is more direct to drive.
Granted, the actual time in the air is much less to the major city city airport.
But, you have travel time to go to the airport, park your car, queue up thru security, partially disrobe -- (shoes, belt, phone, keys, etc. and re-assemble) and then queue up again to get on the plane, find your seat and buckle in, listen intently to the FAA instructions, wait for the plane to taxi around and finally take off.
If you are tall(ish) and are in standard coach, you get to feel like a vertical sardine for the duration of the flight.
The plane lands, taxis, you deplane, visit the restroom, walk back to the main terminal, and if you have checked luggage you need to retrieve that, and then either get a cab, bus, train or rental car (or some combination of them).
And finally arrive at your actual destination (unless the airport was your destination).
All of those activities require time.
This may sound pedantic, but there may also be the parking fee at the airport where you left your car. Multiply that by a couple of days, and you might be looking at another $100 bucks or so.
And that is part of the genius of having superchargers.
They aid travel in a Model S.
They don't take a lot of time for recharging.
And if you can string a couple of them together, you have a viable network that will take you anywhere the road leads....
And to tag onto what Jerry33's thought about driving the Model S: it is indeed fun to drive.
Grins galore.
