But it will have the worst performance where the demand for heating is greatest, ie, when the outside temperature is the lowest. Also high humdity would eat into the efficiency by soaking up latent heat of condensation.
Look at you average parking lot/garage. What do you see? Lots of spaces, and very little wired cabling.
Multi level concrete parking structures have cables clipped to the roof all over the place. An open air parking space has ducts for the cables which power lighting systems. Charging points would be simple to install.
I beg to differ. With my vette set to high idle, I can and will happily idle down the street at 20 MPH in the biggest snow drifts. The secret is in the "snow plow" shaped front end. I just plow my own way...

Have you got the Mr Plow jacket, or does that mean something else these days?
Resistive heating must be over 99% efficient at turning electrical energy into heat. You maybe lose a bit of energy as radio waves, but just a fraction.
I would have to use google. I work in aviation as well so I am familiar with SWAL standards. My only exposure to road transport has been in traffic signaling systems. In a signal controller you woud need the failure of three separate conflict detectors to display a crossed green. The conflict detection there is better than anything I have seen in ATC.
My main problem with your post is that it requires a significant number of unrelated failures. The brakes are not strong enough. The ignition fails to turn off. The gear shift fails to work. I don't know how all these cars are wired but I do know that my Jetta has two sensors on the accelerator pedal. The sensors have to agree on the accelerator setting for the setting to be accepted. That sounds like somebody has given thought to safety in the design.
One of these days I am going to build an EV but I will give it a master switch that I can pull if things go really bad.
But is that a loss of charge or a loss of estimated range? The car may assume that in the cold the heater will be used more so the range is lower, while the charge in the batteries remains the same.
But Broder should have charged the car to full when he charged it. Not doing that on a long drive is stupid. Who fills their tank to 75%?
I have a jetta and while it cruises nicely in a straight line it is an absolute PITA in traffic. The DSG transmission is laggy to the point that you may as well have a rubber band for a throttle linkage.
Primary surveillance works by reflection. Secondary surveillance works with transponders. Here in Australia secondary surveillance radars are being shut down to be replaced with ADS-B but primary radars are being upgraded.
Radar provider Thales has been given government funding by the Technology Strategy Board to investigate how existing TV signals could be used to locate and track aircraft
Thales are just starting out on this. An industrialised solution is therefore a decade away from availability and another ten years from being accepted as a primary source of data on aircraft movements.

My demon agrees with you but he costs a fortune to keep employed.

A Tesla more goes Bzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
Yeah when you want X just ask for 2X then gracefully meet your opponent in the middle.
GPS FTW
Or maybe the estimated range algorithm was extremely conservative, making the driver think there was no way to reach a charger.
Neither will any gas powered sports car.

Yeah I wrecked li-on batteries doing that, early on. Old habits are hard to change.
But if the card is out of range the engine should stop so chuck it out the window.
Or as I like to call them "pedestrian and cyclist killing machines of death".
Yeah I wonder what their plan is for parsing hand signals.
Where does it say that?
Replied to wrong post sorry
A French engineer once started a presentation by saying This is our new product and because we are French it is very complicated.

Car software is not safety certified (as aircraft systems are)
Do you have evidence of that?
Not when they test million dollar cars. Then they are super respectful.
Yeah here in Victoria, Australia new cars indicate 4% fast, so I use my GPS.

Data.

Its weird that we have to set off explosions in our vehicles to make them move.
