charge some sort of energy storage unit (batteries, caps, flywheels, whatever. it's gotta be cheap, not small and light) during off peak hours. Discharge during peak when people plug in their cars. You can even build them way above capacity and feed the power back into the grid during peak hours, causing a net decrease in the amount of energy used.

If I have access to the physical machine I have access to the data.

Ever seen a Thales card payment system HSM? These are the devices that protect your PIN, credit card verification number, bank interchanges, all sorts of different keys. Try getting an encryption key out of one of those:

Not to mention any modern EFTPOS devices, while more compact. are good enough that pretty much anyone can be given one and we can remain confident that the key is safe in there.

When you control the hardware, it is possible to hide the key. Not that I'm saying these devices will never be cracked, but the technology to do so certainly doesn't exist today.

more "pumps"

adding another wire from a power source is much easier, cheaper and space efficient than adding another fuel bowser. A charging station could look like a small parking lot, you take a park, plug your car in, swipe your credit/smart/whatever card, and then you can go and find something else to do for the next 10 minutes (grab a snack, fill your tires, wash your windscreens, huge advantage is you don't need to be sitting there watching the fuel)

In the same space as a petrol station with 10 pumps you could fit at least 20 such parking spots.

and this would actually have the effect of decreasing the load on the power grid, resulting in the burning of less fuel (at least until the demand caught up with them)

the issue with this solution, however, is that if the demand increases too much you can find yourself at a charging station unable to fill up, it's much easier to keep a petrol tank filled.

The main issue with this is then you're locked into a particular type of battery. It has to be a standard size, shape, weight, in order to fit into all cars. This might stop you from making changes to the battery which may increase the performance.

Electricity is pretty much standard across the board, if you can get manufacturers to agree on AC/DC, the voltage and the plug design. Of course, you still have the issue with greedy manufacturers who don't like standardising, but you're not "locked in" as much as you would be with standard batteries.

(I know it would have been pithier to just leave this post at "Audiosurf", and I admit I considered it, but I felt an actual description of the game would be more useful.)

Maybe you should have changed the subject then? That was certainly a very long word!

You're living in a crazy world where everyone has the same requirements as you. I could perfectly own a Model S and never have to take any form of public transport. The car I currently have has a 300km range. I have not once driven 300km in one day since I was legally permitted to drive 8 years ago. I take a plane for journeys longer than that (it's cheaper)

Stick with your ICE car, I don't care, it's clear you're never going to be happy with an electric. But you're an idiot if you think that your driving needs are the same as everyone elses. You've failed to explain how this car is not perfect for my needs. If I could afford $50k I'd buy one.

we are in the shit because it's going to be a long time from the building of the first quantum computer capable of cracking any regular crypto message to the point where everyone can afford one.

During that time, how do you ensure security of your message?
