Sure. We believe that in the long term, autonomous vehicles will be safer. One of the questions that nobody has an answer to today is how long this adoption will take, and I would agree with my colleagues that it will be longer rather than shorter. Our view, as we indicated in our remarks, is that it's not so much because of the automotive technology; it's because of all the surrounding infrastructure that's going to have to be adapted as well. By the time these are widespread, I think you and I will be happy with them, because we'll be in an old folk's home and we'll have some mobility as a result of them.
Absolutely, in the shorter term, are there risks? Yes. That's one of the reasons government needs to be involved in a regulatory capacity, just as it is now with all other vehicles.
