I had two car registrations due and I hate the DMV portal, so I asked Claude to handle it through Plow.
It checked my Plow vault, saw I already had a DMV login and a card stored, and opened a browser on my Mac scoped to dmv.ca.gov. Phone buzzed for permission. I tapped yes.
Only one of my two cars was on MyDMV. The other had a banner saying the DMV no longer had me as registered owner. I'd gotten a paper renewal for it, so Claude used the public lookup (plate + last five of VIN) and pulled the bill anyway. $845 for the newer car. $326 for the older one — blocked, needed smog first.
I didn't know why smog suddenly mattered. Claude looked it up: California exempts cars for eight model years, and 2018 + 8 is 2026. Also my i3 has a range extender, so it's a hybrid, not an EV — no exemption — and the readiness monitors won't pass unless the gas engine has run recently. That would have burned me a second smog-shop trip.
I asked if I should just pay the $326 and deal with smog later. It said no. Pay first and you land in incomplete-renewal: they take the money, hold the sticker, mail you a notice. Deadline's November. Wait a day and do it clean.
Payment method: cards take a 2.1% non-refundable fee (~$18 on the bigger bill). Bank transfer is free. Bank it was.
Vault only holds card-shaped secrets right now, so I stored routing + account as a fake "credit card." Claude asked for that vault item, I approved on my phone, and it filled the form with fill_secret — numbers went vault → field, never through the model. Then it stopped. Page said $845.00 with no fee, name field had no middle initial, and it asked me to confirm the name matched my bank and that I actually wanted to submit.
I said go, and told it to make sure DMV wasn't storing the account. It read the terms, checked the box, hit Pay Now, screenshotted confirmation, closed the session.
Smog shop: just the car, bring the notice, warm the range extender ~20 minutes first, no check-engine light.
One conversation. I never logged into the DMV myself, never read three smog help pages, never compared fees, never almost paid $326 into a hole. It never touched my bank numbers or submitted without asking.
