Several improvements to the automobile during the 1910s made the vehicles a little more "user friendly." Many of the special extra features offered in the previous decade - convertible top, windshield, headlamps, and speedometer - now came standard with the automobile. Safety was improved as well. In 1910, front doors were introduced, the one-man canopy top (a strong canopy that covers both the front and back seat) was standard, and the first all steel body was manufactured. In 1915, a winter canopy top was available, which was solid and featured detachable glass sides. Most cars were still designed to be open, having convertible canopy tops; enclosed cars were significantly more expensive. Other changes in design included the addition of radiator grilles, spare tires carried along the running board, and a hood with rounded panels.
Note in the image below the addition of the front door and windshield and the rounded hood.
The automobile in the image below demonstrates the use of the one-man canopy top. It extends over the front and back seats and is fixed rigidly with side braces.
