whoops.

we bought our own UniPass transponder - cfxway.com/uni/ - and took it to Florida last month, and drove around in a rental car after updating our account to include the rental car license plate. Easy peasy.

Guess what happens if you return the rental car and neglect to update the unipass site, thinking “oh, surely it will only bill me if it actually detects my transponder, not just the license plate.”

well at least now I know where SOMEBODY was driving.

(protip: when you return the rental car, DON’T FORGET to go and unregister its license plate from your transponder account, or you might get billed for wherever the next person is driving. I thought the only thing the tollway would care about is the transponder, but apparently it falls back on license plates too.)
