> What a beautiful car analogy.

Almost but not quite.

Web worked just fine without JS and to some extent still does (this site for example). So a better analogy would be something cars were fine without, but now have it and it improves experience (and sometimes bloats it eg one more thing to break).

Electric windows, seat heaters, GPS, come to mind.

But you can drive on any road without those, while you simply can't use much of the web without JS. I don't think there's a good car analogy.

My comment may have been a little tongue-in-cheek reference to outdated /. humour.

Anyway for the record Karl Benz first produced his Patent-Motorwagen in 1885 whereas the pneumatic tyre wasn't to be invented for another two years and even then in faraway Ireland. So in some some sense cars do predate tyres.

Things are more complicated than that, I'm afraid. Lots of CPU time (and browser complexity) is spent on DOM/CSSOM bindings and the way browser engine handles updates/redraws.
