 Well, we're certainly working on developing solutions for pavement durability to make sure as they come under increased pressure, whether it's in traffic, weather, or anything else, that they last longer than they used to. I don't think you have a solution EV-wise, really, in reality. I would certainly say the development of the technology on the trucking side is less advanced and I think less likely to lend itself to a single technology than on the light-duty side.
