I suspect that their dynamic tolling algorithm is broken. I drove I-66 eastbound this morning and the road was nearly empty until about half a mile before the river. Then it turned into stop-and-go traffic. No surprise, since the HOT portion ends and everyone wants to get across the bridge into DC, which dumps everyone out into slow local streets. It seems like they're trying desperately to limit congestion at this very last part, when it's completely beyond their power anyway. They'll probably have to give up trying to maintain their speed guarantees for the last little bit.
