People's transportation options have changed significantly over time. In the past, wealthy people could buy early automobiles, while average people relied on horses and trains. Now, cars are more affordable and accessible to many. Trains and ships continue to be used for long-distance travel, though planes are faster. In the future, space travel may become possible through ships that can take tourists to space, though initially only the rich may be able to afford it. Transportation technology is constantly advancing and changing how people travel.
