I'll turn to my officials in terms of numbers. The numbers are still very small at this point in time. Certainly, there are vehicles that have some degree of autonomy. As you know, there are five levels of autonomy, five being totally autonomous; you don't even need a driver. Some of these are quite advanced in terms of having features such as keeping in lanes and adaptive speed control, those kinds of things, and they're getting more sophisticated all the time. As you pointed out, many companies are introducing new models.
I don't have an exact count. I don't know if we have that information. I'll turn to my colleagues, but at this point in time it's still very, very small because as we move toward complete automation we need to put a lot of infrastructure in place outside of the vehicles. As well, we need to be in a situation where there are more vehicles on the roads that are communicating between each other.
