Let's just say, I have a higher than average tolerance for car travel.
Still.
I don't find travel by car very efficient. Take, for example, a 15 h drive. If I'm driving, I'm stressed mostly the whole time. I can talk on the phone in some states, but otherwise I just have music or conversation with my passenger to keep me entertained. If I'm the passenger, all I have is music, conversation with the driver, or sleep. I can't read in cars. Even looking at maps for more than 30 seconds results in major carsickness. Ick.
Now, let's consider the same 15 h distance covered by plane instead. True, going through security can be a little hectic. But otherwise, I find airports to be mostly pleasant these days. I can read, play on da internets, or watch people freak out when they miss their connections. I usually end up spending 2 hours at the airport. Add to that the travel time on either end of the trip plus the flying time (about 2.5 hours), and I still come out ahead by a couple of hours.
Nowadays, my rule of thumb is if a driveable destination is more than 10 hours, it is better for me to fly. N.A., however, happily drives 15+ or more hours rather than fly.
How do you decide whether to drive or fly? And more importantly, how do you convince a travel partner that your way is the right way?
