i think i must have had a previous generation FasTrak because my rf transponder didn't have an occupancy setting on it. perhaps i had set it up on the web portal. this was over 10 years ago, from east bay to/from cupertino.

So obvious that I was incorrectly reported by a "fellow" driver when they apparently failed to see my kids riding in the back seat.

Does that setting actually matter? When I lived in the area that had these, I always forgot to set it when the number of passengers in my car changed. I never saw any difference. The charge is the same.
