Ricky Bobby appears to be unhurt, but that Wonder Bread car is toast.

Our reading
An editorial interpretation.
The announcer reports that the driver seems uninjured, then jokes that the bread-branded car is ruined. Calling it toast plays on both the sponsor's product and the slang for being finished, so the wreck is delivered with a cheerful pun rather than solemnity.
