No worries. Thank you very much.
I'm going to move back to Mr. Romano.
Mr. Romano, one of the things about hydrocarbon consumption in vehicles is there is a big excise tax collection from government. It's billions of dollars per year, distributed between the federal government and municipal governments. When you're comparing apples to apples, how do you think this infrastructure money's going to be replaced when you go down the road and we replace these vehicles with zero-emission vehicles?
