The FAA only knows when you last took the BasicMed quiz and attested that you will follow the rules. Getting a physical, storing the form signed by the doctor, and maintaining a valid drivers license are up to the individual.

When you take the BasicMed class, you also have to report when your last physical was. Your physical date is public record is transmitted to the FAA and is part of your Airman Registry record.

Yes, you could lie... but the documentation for the physical is part of your logbook and subject to audit. If I were a CFI, I would be checking that before signing off anyone's BFR. You can't really get away with this for long.
