The one technology, the one alternative, that you use the most is hybrid. But the new area is really electric battery-charged buses. Am I correct on that?
What do you need to massively expand the electric? Is it the charging? We will probably hear from Israel, for example, on the way they charge their cars. Is it charging stations that are most difficult right now? What is the area where you think it could grow the most? It's not natural gas, right? It's mostly the electric cars. Am I correct in that?
