"5 days post-op": You should not drive a car so soon after major surgery, since a sudden stop and stepping on the brake can make the incision open up, and cause repeat surgery as well as extreme anxiety if it does ! Most surgeons will tell a patient to not drive for at least 4-6 weeks after this kind of surgery.

Tradition v evidence: Tradition, common sense, prudence, opinions and precautionary advice usually seem to prevail in the absence of or instead of good scientific evidence. Consulting the surgeon who performed your surgery and who may be the most familiar with your personal-medical-surgical-social history and your physical ability is perhaps the best way to get an educated answer to your question+ inform your decision.
