Killer toyotas?

In my government class today someone presented a news story about toyotas which had uncontrollably accelerated, I found an article on this scary phenomenon. Fortunately the problem is just caused by floor mats jamming up on the gas pedal. I'm glad there is such a simple answer for why the accidents occurred, I was getting concerned that we were having scary killer robot situations where machines try and kill humans, I-toyota maybe?
