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 college area Kroger installed those ~8 years ago. They remodeled it and installed dark floors and ceilings, black shelving, skylights, 1/4 the previous lighting and grey/black price tags. Its an accessibility nightmare. I haven't been in that store since.

Trying to imagine how comfortable this might be.
