Considering the number of Toyotas on the road, compared to the number that have experienced a problem, minus the number that just pushed the wrong pedal, the odds are pretty small of this happening to you.
BUT, having raised a couple of generations that don't know how to drive, haven't got a clue as to how a car actually works, and expect everything to be automatic so they don't have to make a decision, any problem becomes a big deal.
Do away with automatic transmissions, power steering, power brakes, and half the population couldn't get to the fucking supermarket.
