I'm not sure if Tesla is going under or not. But one thing is for sure, if their financial situation gets that bad and their stock tanks accordingly, another company will come in and buy them so the dream will live on no matter what.
Furthermore, I find that a lot of the negative comments about the car itself are all from people that DON'T OWN ONE. As a Model S P100D owner, let me be the first to tell you that the car is absolutely awesome.
There have been comments about there not being many cars at Tesla charging stations. I have owned my car for about 15 months now and I have never once charged my car at a Tesla supercharger. Why? Because upon purchase, all Tesla owners are encouraged to installed a dedicated 240v line and wall charger in their garage, which is what I did. It's like having a gas pump right in your own garage.
I know quite a few other Tesla owners and pretty much all of our driving patterns are all pretty similar. Get up, take the kids to school, drive to work, run a few errands, pick up the kids, drive home. That's pretty much the general routine, and every single owner I know can easily do all that for days on a single charge with no problem. Then when the battery gets low, you just pull into your garage, charge it overnight, and then it's ready to go in the morning. And because you are charging it overnight, the electricity rates are ridiculously low... so low in fact that I can't even tell a difference on my electric bill each month from before when I didn't have a Tesla. Again, 95% of the driving that most Tesla owners are doing is just regular daily driving that a 300 mile range can easily accommodate so no trips to a Tesla supercharger are necessary.
And no matter what you read or hear, the autopilot feature is insane. I take day trips from Orlando to Cocoa Beach or Clearwater Beach all the time and never even touch the brake, accelerator, or steering wheel once. It just takes me where I need to go with zero effort on my part. And after spending the day at the beach with the family, I just pull up the Tesla app on my phone while we are rolling up our stuff on the sand and tell the car to cool itself inside to 72 degrees so it's nice and chilled by the time we walk to the parking lot. It's a total game changer.
In regards to depreciation, drive a brand new luxury car off the showroom floor like a Mercedes or Bentley for 20k miles and then go to trade it in. You'll see that the depreciation is just as drastic with those cars, if not more so.
And finally there's the performance. The Tesla P100D makes Mercedes, BMWs and Bentleys look like they are standing still, and it even makes Ferraris and Lamborghinis look like Hondas and Toyotas. The fact that my 4-door sedan with two trunks will smoke pretty much every exotic car ever made in a quarter mile run is just mind boggling.
Regardless of who ends up owning the majority of the company, Tesla is going to be around for a long, long time.
