Jay Leno has a Doble car (mentioned in the article as a 1920s attempt at a "user-friendly" steam car revival). The video has great production and really shows the starting and driving processes: [VIDEO]

Here is how they solved it in 1925. I feel with our many modern advancements we could do much better. [VIDEO] That said, as neat as steam cars are, there is a reason internal combustion engines won. Probably because they are smaller, lighter and most importantly cheaper.
