I didn't say it would dry up today, I said it'll dry up quickly when the rain stops.
Kind of like if it was thin ice, but it’s actually (mildly) caustic mud.
That said, never tested this on that specific playa. It’s also usually somewhat location dependent even within a specific lakebed.
Don’t be surprised though if it takes months (next year? If there are followup storms) for some of these vehicles to be extracted.
