Actually the meat is probably OK. Most often when Moose get hit it breaks their legs,( they are as tall or taller than a riding horse) and they fall onto the hood. This one probably broke its neck when it hit the seats and stuff.
She's lucky on 2 counts, The moose died instantly, (would YOU want to share the front sat with 1500lbs of freaked out animal ? ) and she was alone. If some one had been in the passenger seat they would NOT have had a good day.
