You’re going on a cross-country trip. Airplane, train, bus, car, or bike?

IF I was going on a cross-country trip I would rather go by car. I don’t do crowded airplanes, crowded buses, and trains. Definitely not on a bike. I prefer to take my time and see famous landmarks or historic sites. I don’t want to feel rushed. I want to experience everything in my own time. I know I would have a grand old time.
