Well, even before electric power steering became popular, rack and pinion steering was/is used in almost all passenger vehicles. The only vehicles that I can think of that use a steering gear and pitman arm like this video are 1 ton Ford/Chevy/Dodge and the Jeep Wrangler.
rack and pinion has been the standard for nearly all smaller passenger vehicles since at least the early 90s.
you can find things like that or like pitman arms on larger/industrial vehicles fairly commonly, though.
to your point, however, yes -- sports cars were the first ones to popularize the method. Rack and pinions tend to feel less 'sloppy' , especially after some use.
The idea stuck around in the industry though because it results in less customer complaints and requires less finesse from the mechanic during install/maintenance.
tuning a 'steering box' is a lost art relegated to hot-rod folks at this point.
So was recirculating ball a halfway point between worm and sector and rack and pinion then?
We have a 1947 Willys CJ-2A, which I believe is worm and sector, though we haven't gotten into the steering yet because there are so many other things wrong with it. Including, it seems, the formerly working brakes. I discovered they had crapped out as I was backing up near a bunch of formerly neatly stacked cinder blocks.
The only recent example I'm aware of is the Ineos Grenadier, and it's quite controversial as it means the steering is a) slow, and b) has very low self-centering (also a function of caster).
Recirculating ball steering also probably won't allow for new fangled features like active lane-keep assist, collision avoidance steering, self-parking, etc. (Which is probably not missed anyways by the 4x4 crowd, including the Ineos Grenadier ideology.) Mercedes switched their G-Class away from recirculating ball steering just a few years ago and I bet, based on MSRP, that their primary use now is much less 4x4 and much more embracing of complex computerized features for urban crawling and highway touring.
I suspect that a problem with rack and pinion 'back in the day' was materials and manufacturing mean they would wear and the steering would get sloppy. Where recirculating ball naturally is low wear. Once they upped materials and manufacturing rack and pinion was simpler and cheaper.
I think for non power assist recirculating ball is nicer because it doesn't transmit road forces back to the driver like rack and pinion does. (Could be wrong)
I was only looking at vehicles from this millennia. 80 series Land Cruiser and 4wd Toyota trucks from the early 90's had a steering gear too, and I'm sure some others that I don't care about.

I thought recirculating ball[0] was commonly used in most passenger vehicles, and rack and pinion was more common in sports cars.

In 1975, your comment would be correct.
In 2005, it's horribly wrong.
Doesn't the XJ have a steering box as well?
