Hmm, two sons 14 years, three 12 years old? If 3 or 4 are nearly as smart as Elon and study science and engineering,
he may have several more talented and trusted right hand men to help run Tesla starting in mid 2020s.

CR would rate your living room couch as superior to any car they rated if they used the same scale. So safe.

Exactly the same conditions transmissions, bearings, differentials, and transaxles have always dealt with. I'd expect minimal to no increased wear from such conditions.
News of the judge approving the joint statement should at this point be $280+. Definitely expect buyers leading up to Q3 financials.
I can see it now... Alice summons the car that she shares with Bob down the road, but before it arrives Bob summons it back...I've seen this story already with Netflix. The highest adoption rate was with the youngest demographics. But then what happened is they all shared their accounts. Same thing will happen here.

Random question - why doesn't Tesla create it's own dealerships and roll them up under a wholly owned subsidiary? They could use these in the states are have very restrictive laws requiring dealers (unless the laws stipulate that the car company can't own the dealer), rather than fighting it out w/ all these states. Tesla is sticking to their guns, fighting for their ideals, but I don't see the downside to "bending" on this particular battle.

I don't think its possible to heat the battery w/o also heating the motor and gearbox, since the heat source for the battery is the rear cooling loop (power electronics, motor, gearbox). Ingineerix released a video on the cooling system architecture (embedded below).
"Ingineer" (link to DISQUS profile) traces the components from front to rear in this overview video:
- Coolant reservoir
- 2 coolant pumps
- 4-way valve:
- small portion of coolant flow used to cool the computers at front of Model 3
- AC unit can be used to chill coolant below ambient temp during supercharging
- small portion of coolant flow used to cool the computers at front of Model 3
- 4 coolant inputs at the front of the battery pack
- 2 coolant outlets at the rear of the battery pack
- Y-manifold in rear leads to another 4 way valve
- forms a series connection to rear powertrain cooling loop:
- PCS (power conversion system)
- charger
- DC/DC converter
- Inverter (motor controller)
- gear train:
- oil cooler
- separate oil pump
- oil filter
- heated glycol returned via rear 4-way valve, then routed to heat the battery pack
- PCS (power conversion system)
So to preheat the battery, they put the drivetrain into a heat generating mode, and cycle gycol coolant from the PCS through the motor, gearbox and battery in a loop. The 2 sets of 4-way valves in the coolant system allow various parts of the loops to be isolated or flow regulated. Ingenious Ingeneering, Eye'd say.
Model 3 preheats the battery by transferring heat from the power electronics and power train. So the powertrain is automatically and necessarily preheated as well.
Cheers!

Thank you, that is very useful information!
This should be one of the design decisions leading to the extremely long 1 million miles longevity of the drive train I think: not driving with insufficient lubrication at all (with a too cold gearbox) should make quite a difference I think.

I would love Porsche to IPO for 81bln Porsche IPO Could Value Carmaker as High as $81 Billion, CFO Says. It would definitely help with TSLA valuation.

State laws disallow that. They only allow dealerships that are actually independent of the manufacturer.
Remember, state laws were written when dealers feared OEMs will directly sell, bypassing the dealers. Dealers had put in a lot of investment and they would lose out.
But now, the same laws have become a protection racket.

Dunno - while a company selling lubricants is not a particularly authoritative source:
Combat the Effects of Cold Temperatures
"Automatic transmissions can shift harder in the cold, but changes in transmission performance brought on by cold temperatures are usually more pronounced for drivers who operate manual transmissions. As transmission fluid thickens in the cold, the synchronizers in manual transmissions cannot spin as quickly as they need to, which can severely impact the driver’s ability to shift until the fluid is warmed enough to provide proper flow – and protection."

Plus a Tesla gearbox is much simpler than an automatic transmission.
Also, @Artful Dodger pointed out that the Tesla gearbox can be heated, so I guess my argument is moot from that angle as well.
I kinda feel bad for Elon in that he's in serious need of a light exercise and good eating program. He used to be in somewhat good shape. He's 47 now, which is right around when the old body can't hold it together as it used to without some proper light exercise and good eating habits. 45 was the age that I started developing a serious pot belly and I almost gave into it, but decided to change my eating habits. Lost 20 pounds, got rid of the pot belly. I hope he figures this out...
But the Dad bod is in man....
Not talking currently. Between 20-50 years from now. Obviously, all ICE need eradicated. If cars are electric/software oriented, it will be a lot easier to try to mandate such things. Internet will be free & high bandwidth, provided by satellites Elon is about to launch, right?
(project Starlink)So, it won't be expensive. And easily 100%, although a fallback solution will still be needed.

I made a comment to support Tesla on the site. Please spread awareness. Do your part if you care.
Why you can't buy a Tesla in these states
Pogue is an excellent journalist who specializes in technology. Always worth a read.
Ford privilégie la fermeture de l’usine de Blanquefort, un choix « indéfendable » pour Le Maire
French newspaper LeMonde talking about how Ford is closing down a factory in Blanquefort, Gironde costing jobs to around 847 people. Hope those good people can find a job somewhere else -- preferably Tesla
