I have to agree with your logic. The track is a much more controlled environment. You worry about her getting scared when someone passes her on the track, but passing (no matter how close) is expected. It is much easier to deal with that than the unexpected oncoming left turn, the no-look merge, or the old lady pulling out of her driveway.
Ultimately, it is her call. If she is willing to take the risk of street riding, you have to respect that.
Also, you talk about being anal. You should help her with the basics and that's it. Overly critiquing you wife will cause nothing but problems. Sit back, let Zort do more of the instructing and you do more of the encouraging.
