Volvo didn’t do it first though. The approach at Tesla has always been to make a competitive electric vehicle market. They did that. Musk has even said he doesn’t care if Tesla fails as long as it gets automakers to build electric vehicles. Teslas success shows automakers it is possible. Tesla has already succeeded in its original mission.
No but as I said, Musk's mission with Tesla was to make BEVs widely available. Tesla may never be able to make a cheap BEV but they have grown the market and driven economies of scale that allow others to make competitive BEVs.
