Interesting. I have FSD and had the MCU2 and HW3 upgrades at the same time, hence the gap in knowledge. As I previously mentioned, cones were visible on HW2.5 vehicles with MCU2, but not with MCU1. Is that still the case (does your Tesla with HW2.5 & MCU2 show cones)? If not, then maybe something else is going on in your case (or maybe they silently changed it with v11). If so, perhaps they started including the HW3.0 upgrade in hopes of selling FSD later by way of the FSD visualization preview, otherwise it seems odd that they'd even offer the preview unless you had already paid for FSD. Either way, I do now vaguely remember that setting making the stoplights show up, but I turned it on immediately after upgrade, and I guess I assumed it was only available for people who paid (vs being HW specific). Still, prior to upgrade, my HW2.5 MCU1 config had an option to warn for red lights, and that included sound when red lights were detected. It didn't always catch the red, and sometimes it went off in spite of green (presumably because of red arrows over other lanes). I suppose they could have removed that in v11, or it could be FSD only, except you talk like you have a newer version of that and indicate you don't have FSD.
