It's news because it wasn't known before and it tells us a lot about Google that we've only had hints on before. It's also an interesting recap on the early days of Tesla. Tesla wouldn't be the first company that released (despite their best efforts, I'm not blaming them) overpriced underspec'd crap at the beginning that could have severely dented their future business, but it's often hard to remember that.
Remember the original iPhone? EDGE only? Required special SIM cards? Barely supported text messaging, and didn't support MMS messages at all? Didn't run third party apps at all? You don't? Nobody does? It's true!
Yet the iPhone survived all that and nobody remembers how awful the first version was. Turns out Tesla's original sedans were a similar story. I didn't know that. I thought they were always cutting edge.
