Prejudging what? That he is promoting the idea that crashed vehicles in salvage yards have suspension issues when the front ends have clearly been smashed to bits? You can go through the same salvage sites for BMW's, Mercedes, Cadillac and claim that all of those also have suspension problems that led to their crashes. Doesn't make it true.
Mr. Cordano and Mr. Wivaneff have pre-judged. We are responding to their pre-judgement.
There are plenty of people betting against TSLA. The short interest is very high. Plenty of lies and innuendos are pushed by people betting against TSLA day in and day out. Mr. Wivaneff frequents the Yahoo finance boards to rail against Tesla and has a long history of lunacy in this regard. You draw your own conclusions based on that.
Now, Mr. Cordano might not be in it for stock gains either way, but he is clearly in it for something. Maybe it's to get Tesla to cover his entire repair under good will. But in doing so, he's taken the stance that all Model S's have this quality problem. He's the one pre-judging and he's drawn in support from well known trolls to promote his agenda. That's disgusting.
Neither person really is about making Tesla's safer.
