Indeed, yes. Thank you for the question.
First of all, I agree with my colleague here. The big issue for government is that there are three different sectors of the issue, which makes it more complicated. There's the technology, the innovation and research and development. That's moving ahead pretty well at the moment.
Second, there is the regulatory framework. I don't like unnecessary government intervention, but as David has mentioned, there are issues about privacy and issues about the regulatory framework. I know that General Motors has in fact requested of the U.S. government certain changes to vehicle safety regulations, which is one of the ways that government must be involved. GM has announced that they will start mass-producing driverless vehicles in 2019, next year, and they've requested a number of variances to the safety regulations, not to make cars less safe but to be realistic. Regulations in Canada and the U.S. at the moment require that there be an airbag tucked inside the steering wheel. If there's no steering wheel, that makes no sense. What GM is proposing is to treat both front seats in a car the same way, the same way that a passenger seat, at the moment, is controlled.
