IMHO there is only one way to compare cars and FOSS / FreeBSD:
In the outside world people want options to choose from, personalize. Alike coffee and cars, it should be tweaked to the individuals' needs and taste.
How different with computer software: the majority of computer users buy a box with a standard Operating System on it. No questions asked, one flavour fits all*). The urge to personalization limits to a wallpaper and a dark theme.
When cars were like computers, the streeds would be full of Trabants. You could choose a colour, but no guarantee you would get it. When ever.**)
Motorcyclists probably are more like FOSS/FBSD -- you hardly see many of the same model at the same time. Your bike depicts your choices.***)
*) OK, two OSses. Wadnows and Apple. The second one is for those with more money.
**) These days Trabants will be replaced by Teslae. They come in the colors white and black. When it's broken, there seems to be no guarantee for spare parts. Sounds pretty 'GDR-ish' (color instead of the proper spelled colour, because it is an American car).
***) Over here the BWM GS Adventure might be an exception. See my remarks on the fruit company above.
