Last trip to TV, I ended up in the wrong lane on the tollway...Sunpass only lane. Once you're there, there isn't much you can do, so I went on through. I was in a rental car, so when I got back to Germany, I saw an extra $7.00 charge on my bill for the toll I missed. Bet it happens alot, with travelers who are not used to our toll systems... Rental car companies probably get a volume discount ...
