Dirtiest car ever ?
 

Alex Tremulis shared the info,I found this image in an old book

A self-propelled parachute?

Top speed of 25mph?

Well, at least it has low mass...

Those old cars really did not move very fast. This one more like 15 mph most of the time -- 20 would scare granny spitless. Most could not outrun a horse.

With the wheels and running gear (versus the parachute as mentioned), aerodynamics versus mechanical drag, I wonder which was actually higher?

As I recall, they said they did not need a speedometer, "When my Ford is running five miles an hour, the fender rattles; twelve miles an hour my teeth rattle; and fifteen miles an hour the transmission drops out."

I'm sure the cow patty and horse road apple deflecting front fenders were good at what they were intended to do.

"...green road apples..." can really be nasty!
