The Dragon escape thrusters are only for launch failures that happen at the launchpad. The rocket was at Max Q when it exploded, so there's no way it would have deployed.
For a home battery pack, $3K is almost nothing compared to a home's total price. The average cost of a home in California is at least $400,000.
It doesn't have to be used in a crime. All cell phone switch cell towers while you travel... your cell provider it keeps a timestamp log of this switching whether you use your phone or not. If you are suspected of a crime, all they need to do is guess your (plausible) location and see if your phone agrees. If you have an accomplice with a cell phone, he will mirror/intersect the same locations as you... and finding plausible accomplices would be as easy as going through your phone's call/SMS communication records..
This should be blatantly obvious to anybody that knows anything about wireless tech.. Your phone carrier MUST know which cell tower you're near, simply because it's required to have your phone work at all.. And it's trivial to keep a log of such connections; some carriers keep it for 30 days, some for 6 months.
My guess is that they're counting on the ignorance of the average criminal to NOT know that fact, which makes the job for the police much easier...
You didn't quite read his reply: You are an edge case.. not a typical user. Because of that, the emerging technologies in this field won't target your requirements for a very long time. You're like a truck driver complaining that Tesla won't build an all-electric semi truck...
Who said he's going to sell it?
With a Volt he can optionally plug it to grid and get infinite mpg.. There's no chance of doing that with a diesel.
Granted he's have to pay for grid power... but even the most efficient diesel doesn't beat an electric car on raw energy cost per mile.
Most electrics are bought as a 2nd car, since a vast majority of people don't driver further then 50 miles a day. So the range anxiety may be a moot thing, since lots of people use their gas car (or choose to fly) rather then worry about driving their electric car across the country..
Apple-- (specifically Steve Jobs) figured it out long ago: Cramming all sorts of technology into a thing does not make that thing useful; it takes an overall humanistic approach... involving psychology, human intuition, and aesthetics.
If design wasn't important, why else would Android start off as blackberry clone but turn into an iPhone clone within a matter of months?
Actually, the smarter self driving cars CAN handle various obstacles such as road construction and lane closures. See https://www.youtube.com/watch?...
Capacity can be smoothened out with battery storage-- that's where someplace like Tesla's Gigafactory comes in; it drops the price LiOn batteries by 30%, while the used batteries can then be sent off to solar farms to hold excess capacity, releasing it at night.
Tesla admits they're using only 20% of the former NUMMI plant space to build the Model S/X.. which is supposed to be low volume/high price flagship vehicle. They're still designing the Model 3's manufacturing method (alongside the vehicle itself)..

Perhaps they're planning to use Tesla's Gigafactory as a supplier.. From what I hear Tesla plans to sell excess batteries to the open market --not just for their own vehicles. The whole point of the Gigafactory is to drop the worldwide price of Li-On batteries by 30%.
You make it sound like people won't be plugging their cars when while they're sleeping...
