not op, but i assumed the 'upfront' would fund the rides as well, vs. just 'unlocking' them. i read it as more of an initial prepayment.
Same; this is how it read to me. I was confused seeing this in the comments.
The unclear part was the portion where you select how many rides you want. $30/40 rides doesn't exactly clearly imply that you're paying to pay for flat rates. Not saying that it's not on the page, or that they're hiding details, just that they definitely obscured that element.
Agree, not really sure what the alternative would be?
