Chris Murphy:

So you see this being used most likely on roads dedicated to driverless cars?
 
 Or lanes that are dedicated to it, so that all the cars are behaving nicely, playing nicely.
 
 Generally speaking, how does the technology work?
 
 These cars have radar and lidar sensing what’s around you and how close it is and what the terrain is. So it’s the vehicle sensing its surroundings and then, of course, it has a path. Somebody’s going to have to tell it where to go, just like GPS. And then from there, it has to know properties of the highway, turning restrictions, speed limits and things like that that are on databases.
 
 Would there be special infrastructural needs for driverless cars?
 
 If we ever want to implement something like this, we have to be careful and make sure that the striping on the roads is really in good shape because these things are going to depend on that. It will be sensing to stay in its lane, so it’s got to know where its lane is.
