So do roads, and your metal cage literally has a code on a plaque tied directly to your government ID, with a retroreflective background and each character carefully engineered to be machine readable from any angle and lighting. Hell, a good number of the cars you pass have 360 degree camera arrays pointed directly in your windows, or if you spring for a higher end model with all the features, you get the privilege of a camera pointed straight at your face and at your passengers’ faces.
Also, you can cover your face on transit with something like a medical mask and sunglasses. If you try covering your license plate you’ll literally get arrested.



























No, but they can still severely harm your computer/data. Unprivileged programs can still delete or encrypt everything in your home directory or inject themselves into other unprivileged programs or a commonly used shortcut file. You’re probably thinking of containerized apps which much more limited than the default user permissions and access can be given only to what is needed instead of everything your user has access to.
Linux is as susceptible to this as Windows. In fact it’s even easier on Linux because you have access to full featured scripting languages. It’s not that hard to write a proof of concept malware in Python that copies itself to somewhere in your home directory and appends
python ~/.some-boring-config-directory-most-people-never-open/persist.pyto your bashrc.Any modern operating system is so complex and has so many parts interacting with each other that it’s always possible to hide come thing malicious somewhere in the Rube Goldberg machine which most people will never notice. Linux can be said to be better than Windows in this regard due to being open source and auditable (and generally less Rube Goldbergy), but it is definitely not immune.
