Yes. It's a safety issue. But there are also at least tens of millions of cars on the road without backup cameras.

Lack of rear visibility without a camera is a much more of an issue on newer cars; older cars, which make up the bulk of those "tens of millions", don't have such a serious problem.

That's fair. Even when I shopped for a car over a decade ago, it felt like some of the electronic safety systems were making up for lack of the sort of sightlines you had historically. One of the reasons I ended up going with a pretty old-school SUV design even though I didn't have much of an interest in most of the off-road features. Would probably buy the same vehicle today even though it hasn't been updated a lot.

Yes, and of course there are exceptions. I bought a new Toyota 20 years ago that probably had worse rearward visibility than some of the Teslas that are being recalled.

I'm not (directly) saying it's a safety issue, I'm saying it's a compliance issue. It is clear that it needs fixed because it's clear that this function is required by law.

Of course it needs to be fixed.
