One U. S. Senator suspects GM is involved in covering up responsibility for the ignition switch problem that killed 13 people.

However, Dr. David Cole of the Center for Automotive Research in Ann Arbor tells WOOD TV that's entirely unlikely. 

Cole is  the Center's Chairman Emeritus who says cars are extremely complex, so finding a problem can a lot of time. 

Besides which, he says "in this day and age" people have learned that "you can't hide things".

He said that the cover-up, which will be exposed eventually "is worse than the sin that was committed."
