When traveling, I prefer an airplane to a luxurious car. Yeah, for a number of reasons. Personally, I like having much comfort-ability as much as possible when I am traveling. The luxurious car also seems comfortable, though, but not as the airplane. The highest luxury a car can provide is still less than the luxury, and the average plane can provide. Especially when it comes to first-class airplanes, you will feel so much at home.
I can be able to take my shower in an airplane with in-flight showers, which is not possible in any luxurious car. I can easily access the toilet in an airplane if I am pressed, but I doubt if any luxurious car can provide me such. However, work done per time for me is what I really look into. An airplane will provide me with a higher speed compared to a luxurious car. I really do prefer traveling by airplane to traveling in a luxurious car.
