This demonstration also assume that the user would not swerve and try to prevent the accident. I think human instinct is to swerve and try not to get into the accident. So I think you’ll rarely find a direct head on collision like this. If the user try to swerve, there’s more chance the SUV will flip. Add in a off angle collision while both cars try to swerve and I think you’ll amplify the chance of flipping. That’s just my 2 peso.
