Did you try measuring the power at the wall end of the cord while the heater was running? Most space heaters aren't very smart, and it wouldn't surprise me if the draw varied wildly depending on the power supply and how warmed up the heater is (I know mine will go between 1 and 1.5kW plugged straight into the wall as it warms up).

I'd be surprised if a 100-foot extension always consumed 850 watts.

Yeah Tesla saved the guy 40k, how rude

I think it was more the fact that Tesla didn't tell their customers they had GPS tracking equipment fitted to their vehicles. If a service manager could access the location information I'd imagine quite a few other staff at Tesla could too ...

I'm pretty sure they have been open about this. At least I remember reading this somewhere on their website. I think it was part of their 'product testing' program or something, where you would allow Tesla to track everything to gather data for their purposes to make the car better.

That seems like something that should really fail open, for exactly those kind of situations.

I dunno, that would mean that a bricked roadster on a hill would possibly roll away.

Whatever happened to good old parking brakes? Sometimes, low-tech is better.

Why can't you plug the car in, and switch on tow mode? Even a laptop with a dead battery works fine when plugged in. I'd venture to say that a tow truck's alternator should be enough to disengage the wheels. Sorry, but this is just crappy engineering.

Unlike a laptop, the Tesla was never designed to be run while plugged in. Combined with the fact that they arent designed to hit zero battery. This is an easy oversight of design, where the laptop can run directly off of wall power not due to fix the problem of a dead battery, but to provide less stress on the battery while being used and plugged in. A usage case that does not exist under normal usage of a tesla. Add…

Which is actually an amusing thought. Perhaps they could ship them with really long extension chords, just enough for a city-commute...

I'm much more in favor of hundreds of millions of govt money going towards 50-100MPG+ electric/gas hybrids than all electric at this point. Limited range, hard to "refuel", and now the very real possibility of bricking. I think we are still a long long ways away from practical all electrics.

I'd prefer the government stay out of it all together. Producing vehicles isn't what the government is for. Second, using a 2500 pound car to transport a 150 pound person 15-20 miles to work every day is incredibly inefficient any way you look at it. If the government is going to be involved at all, it should be to promote walking, cycling, and public transportation. Researching more efficient cars is like trying to…

We'd be far better off if government weren't subsidizing the automobile at all. Subsidizing mass transit to ameliorate the effects of subsidizing the automobile makes no sense.

I don't think it needs to promote walking either. Most people are perfectly capable of understanding their own situations if we don't hide the costs and if they are allowed to learn from their own mistakes.

It would be proper to tax things that have negative effects that aren't paid for, such as pollution.
