I played with the Geico example, and it seems to do a good job on the happy path there. But I tried another one where it struggled... I want to get me car rental prices from https://www.costcotravel.com/. I gave it airport + time of pickup and dropoff, but it struggled to hit the "rental car" tab. It got caught up on hitting the Rental Car button at the top, which brings up a popup that it doesn't seem to read.
When I put in https://www.costcotravel.com/Rental-Cars, it entered JFK into the pickup location, but then failed to click the popup.
