You can't kill some memes. And people want a simple answer to complex
problems.

There's a simple solution. Make the display such that the driver can't
see it when the vehicle is in motion. I don't care if it's as crude as
a physical screen that deploys to block the driver's view, or as
expensive as two displays--one for the passenger-side, one visible from
the driver's seat only when the vehicle is in park; or as elegant as a
software-driven restricted view for the driver when not in park (e.g.,
maybe a polarized screen and software modification to the display).
The simple answer is stop the driver from accessing/seeing the display.
The method shouldn't be driven by the usual automotive "save a penny"
mindset.

I don't know of any WiFi tool that doesn't show all channels, whether
with or without SSID.

The desision on what to represent a SSID-less channel should be documented.
I don't have a problem with showing "?" if you don't know the SSID; just
document that's what you're doing.
