You don’t even need to go that far (and speed limit restrictions would never fly anyway), just increase registration fees for vehicles bigger/heavier than X unless the vehicle is certified (under penalty of perjury) commercial use only. If these drivers had to pay 5 grand a year for registration, they might rethink life. “Mixed use” and “farm” also needs to also die.
