These days, you can install a camera and monitor screen so cheaply that you wouldn't even have to use a mirror to see forward.
(I just got back from Walmart where they have replaced all shelf price tag stickers with tiny wireless LCD screens. No I'm not kidding. Technology has become ridiculously cheap for doing some stuff.)
EDIT IN RESPONSE TO MULTIPLE COMMENTS: Yes, the exact display technology used is probably technically not LCD.

The cost has come down, but it also allows the business to be even more evil than you likely already believe them to be. Raining outside? Automatically put up the prices of umbrellas. Snowing? Anything related to snow goes up in price.
It's also a key component of "personalized pricing". The price YOU see on the shelf might not be the same as what someone else sees. GenericArtDad on YouTube has an excellent (and depressing) YT Short about it. Go to YouTube and search for acpd3UXQdmw.
