loads of commenters in this thread are saying that when cars part it doesn’t form “an uninterrupted lane” because inevitably there are obstacles, like people who don’t do it, or don’t leave enough room, or what have you.
shoulders aren’t really littered with broken down cars.

Shoulders are still for emergency stops even when the traffic is standing & ppl might leave their vehicles.
The middle of the road is more traveled & is on average cleaner of debris that could eg damage a tyre. Also less chances of ppl walking there.
It’s just that someone improved on a working shoulder system with a statistically a bit better one (that works even in cases where there is no shoulder). And it didn’t cost much (basically just marketing to get ppl to understand it).
