This is a way to tell if something is social media or attention media.

"Surfacing the best comments" is only a problem at scale. And attention media demands scale whereas your social circles break down at scale. Commerce sites (like Yelp or Amazon) also demand scale, so they also have a "surfacing the best" mechanism.

It's a cost-benefit analysis like many other things. There are limited resources, they should be spent on investigating cases that have a chance of getting closed.

Cold cases might get reopened because of advances in technology or other changes over time.

Late reply, but did your colleague go from ICE BMWs to an EV Model 3? For me, zero maintenance and no more stopping at gas stations (you need a charger at home) were HUGE advantages to switching to an EV. So I also really liked switching from ICE to Tesla EV.

But I also much prefer my EV BMW to my previous Teslas. Nicer to drive, nicer features (better sound, HUD, sunroof), hardware controls, door handles that you can open with either hand, better in weather (no rain in the trunk).

My family complains the i4 has a smaller cabin, but the driver's seat feels just fine to me. :D

Not saying please or having to be polite is often simpler.

Knowing and using etiquette is often more effective.

If we're comparing notes, I traded in my Model 3 for a BMW i4 and I couldn't be happier. It's a nicer car and more fun to drive!

JD Power and Consumer Reports both rate BMW above average.

BTW, my impression of BMW maintenance from prior decades is expensive and not great reliability. I care about it less now with EVs because there is so much less regular maintenance. No oil changes, no brake pad changes, etc.
