I'm imagining this in two phases: phase one - you drive around, and excess energy goes to compressing air. Phase two - you use that compressed air which takes very little additional power, so you get to double up on force. I guess likely a 'running mode' where it's using some power to keep suction on.
I'm curious how much time you get at full blast vs 'just' enough to keep the car pinned to a wall, e.g. 1 vs 2 g.
It still doesn’t make much sense to me. And that’s before considering what happens when you get rocket stream hitting a tarmac road. Never mind public roads, this sounds like a major hazard anywhere. Plus the quantity of compressed gas son board (if that’s how it works)… not a pretty crash. At these numbers, imagine 10MJ released all of a sudden - apparently that’s about 2.5kg of TNT.
Surely I’m missing something… as I say, I can’t make sense of it.
ETA: this is a horrifying amount of energy to be sitting on top of.
It's an electric car - unless you've got an incredibly long charging cable, there is no "excess energy" when you're driving around.
napkins, and envelopes at least kind of make sense.
Who was ever writing on the back of cigarette packs?
British officers planning trench raids in the front lines during WWI. Or, at least, that's where I've been told the expression originates.
Really, though, is it impossible to imagine no one, ever, using a cigarette pack to jot something down? It's a colloquialism. It doesn't even have to be taken literally to make sense. What is gained by questioning it on that level?
Wouldn't the back have printing on it? I could imagine someone ripping the pack open and writing on the insides, which are blank.
I took the OP's question to really be a question about the origin of that phrase, and with your answer, I learned something I didn't know before. So I, for one, am happy the question was asked.
The OP's question was clearly skeptical though:

Implication being that writing on the back of cig packs does not make sense. I'd agree with your reading if not for the "at least kind of make sense" bit.
