Chuck, your story grounded my memories with a thud. You're right--we did put up with a lot of physical discomfort back then. I think I remember a friend driving the Safari on the beach with the windshield up--but no roof, no doors. Ah, youth!
Worry about rocks, cigarettes, bottles & tires. My time on a motorcycle is long over but I have been hit with a few small rocks. One cigarette butt and another flew past my helmet. Saw a semi truck tire bounding down the highway one morning. Looked like it missed everyone. My truck has taken two egg sized rocks to the windshield. Oh I went through a hail storm - that stung! Then there was the motorcyclist who followed my uncovered load of sand. He passed after a couple of miles. I could tell he was having problems.
I saw at the NAIAS 2013 the version of the car with roof and doors in a metallic orange color and was very eye catching. Also I saw the design student's concept cars with ideas like the one presented here (some for snowboarders), others for other sports or things, as if they were designing a car for themselves or specific niches. This Smart EV No Doors or windows, looks as an unfinished Smart, but it's only and will remain as concept car or be consider with bikes or golf cars, it would not pass NHTS safety for general use.
Linear guides are one of the most important components required for the development of automated or computer-controlled equipment. Aluminum profile extrusions, used for these guides in machine design, can enable designed-in functional features.
