After going through all that, I just get a page full of "N/A" as quotes. Cool idea though.

Yes, total and complete fail, after going through what seems like a pretty standard 2-driver use case.

There's no sort of progress meter, so I don't know how long I have to wait, and after the N/A quotes there's still a spinner running, so I'm unsure as to whether I should wait, or what.

Idea: great. Execution: really sub-par.

Sorry about that -- something seems to have slipped through and we're working to replicate the errors and fix them.

Same here. I actually have to renew my policy by September 1, so I was hoping this would be a fun experiment!
