It sounds like you had a tough examiner, but aside from the yellow (you can definitely cause an accident coming to a full stop on yellow around here), he also had comments about steering, brake pressure, and signaling. Did those make sense to you? If so, you learned a lot and will probably pass next time.

For most people, this is close to the “best” they’ll ever drive, as far as adhering to the law, which is different than the confidence gained through driving over time. So he’s being a stickler and maybe even noticing stuff that could turn into future bad habits. And yes, there are tons of licensed terrible, distracted drivers.

Deep breath, and good luck.
