The Stanley Steamer, for instance, seemed like a sound innovation, but it simply could not compete with the internal combustion engine. The blimp is still used, but more for observation and advertising, rather than transportation for large groups. All of these failures in technology helped lead innovators to other solutions and ideas, and so, they may not have truly been failures at all.

Finally, a look at technology and transportation should look to the future, as well. Will supersonic flight ever really exist for a majority of people? What will cars of the future look like? Will we ever break our dependence on fossil fuels and create alternative forms of energy to fuel our transportation needs of the future? Innovation has always existed...
