You will see stuff in a car, especially out west. Seeing things doesn’t really have relevance unless we are talking hundreds of miles per hour. A bike is slower than a car.
As convenience goes, we are talking about using a bike, not going on a train.
As far as comfort goes, a car is more comfortable than a bike. If you disagree, you only know economy cars.
I don’t even know if America has passenger trains with car carrying. I believe that is a thing in Europe and maybe Asia.
