I may have a bit of a different perspective, and let me tell you why. When you own a fleet of delivery vehicles, you can buy an application to track all of those vehicles. If someone stops at a Tim Hortons for more than 15 minutes, it will tell you. That technology is in your cellphone.
That technology, I believe, is going to be far more adoptable today, rather than grade separation and all of those things. We can put that into driving cars today to prevent going into a lane that has, let's say, autonomous vehicles in it. We have the technology today to do that, and we're implementing it today for UAVs. We're just putting a propeller onto the cellphone to manage it.
One of the things that was mentioned by Bern is called geofencing. This technology is now widespread out there. It makes sure that autonomous systems or unmanned systems do not go past a geographical barrier, and it goes right into the control system. The technology is here today. It is very simple to adopt it in a manually driven car.
