If you were to be in an accident, would you rather be in an Expidition, or a Miata?

Oh come on, that's just being silly. How many people out there are driving Miatas because they didn't want something as big as an Expedition ?

If you want to compare cars and their crash survivability then compare two that are aimed at even vaguely similar markets. Like a Volvo XC70 or something (yes I know a Volvo XC70 isn't directly comparable with the Expedition, but at least it's in the ball park).

And for the record, my Jeep Cherokee saved my life in a head-on collision.

No offence, but how do you know the fact that you were in a Jeep saved your life ? Did you try out the accident in a range of other cars, some of which didn't save your life ?
