This is a promotional film from Dodge produced in the 1920s. Getting around in the mud at an oil field doesn’t look all that pleasant, but the point is that you could actually get there in these conditions, which was a great selling point before we had all these paved roads everywhere. Note that you could roll the whole thing and the windows wouldn’t even break. However, this is a promotional video, and there had to be outtakes. You don’t show off your failures.
According to Classic Lantern, who uploaded this video, Dodge installed electric starters, generators, and lights on their cars beginning in 1914. I don’t imagine there was anything like a suspension or shock absorbers. -via the Presurfer
