It matters to someone like me. The range of current Telsa's is just on the edge of what I need under normal conditions, which means that it falls short (fails)

It matters to someone like me. The range of current Telsa's is just on the edge of what I need under normal conditions, which means that it falls short (fails) under worst case winter conditions. When I'm driving around to a few customer locations during a work day, I don't want to be wasting time sitting around waiting for my car to charge as that's time I don't get paid for. 747 miles range would mean it handles the worst days, and even handle the case of driving to a data center in another major city round trip. It's nice to finally see a company pushing the range envelope a bit further!
