I would take it as such that Toyota just happened to be the first to get hit by this. The others are no less vulnerable. As software propagates into the design

I would take it as such that Toyota just happened to be the first to get hit by this. The others are no less vulnerable. As software propagates into the design of previously mechanical products, we'll get more of these. There must be lots of bugs in other car models and makes that could surface anytime. Avionics software does keep planes in air but if you applied the same level of rigor to making automotive software nobody could afford the cars.
