Count me in the camp that does. My TV runs GoogleOS (Android), and it's great, because I don't need some other device plugged in to do what I want to do with it. There's only 2 things I want from this thing:
1. Playing external media. It has a USB port, so I can plug in thumb drives and play video files from them. The built-in OS works fine for this, and seems to handle any media file or codec I throw at it.
2. Playing YouTube with a good player. Since it's Android, I can load APKs from wherever I want, and so I installed "SmartTubeNext", which blocks ads and sponsor segments automatically. It works almost too well.
I think the mistake most other people make with smart TVs is that they get ones with crappy proprietary OSes, so with those you have no control over anything and can't run any 3rd-party software like SmartTubeNext. Of course, eventually this model could lose support from the mfgr, causing security issues or not being compatible with the apps I want, but for now it's quite nice.

A good example of this might be the lack of intuitive feedback regarding headlights. More and more, dash lights stay on despite exterior lights being off, giving the driver the impression that everything is normal. IIRC several countries including Canada are moving to require exterior lights to be on at all times now, but it boggles my mind that such a simple to understand phenomenon with so many straightforward solutions has to be solved through regulation instead of the automakers just, you know… doing better.
Still, despite a clear design defect and recognition by regulator agencies, no litigation is likely to occur.
I'm inclined to think it shouldn't. Cars are highly regulated. There are a great many very specific standards cars have to meet to be legal to sell for road use in most countries. There's stuff we all know about like crash testing for occupants, and more recently for pedestrians, but there's also weird stuff like cars not being allowed to have required lighting on movable bodywork in the US market[0].
I'd set a much higher bar for defective product claims when the design of the product is already subject to a great deal of specific regulation. Courts do not have expertise in car design and are probably worse at specifying design standards for cars than regulatory agencies staffed with experts and dedicated to that task. As you mention, there's a regulatory solution to the problem you're describing already in use in some countries.
