Amongst technology enthusiasts in the US.
Here in The Soviet Republic of Yurop, gas is $8 a gallon and is only going up from there. If people know the name Tesla, it's probably because they've seen the Roadster lampooned on Top Gear. However, people are talking about Renault and Peugeot and Nissan's EVs. Not car enthusiasts, but ordinary people who've seen the cost of fuel more than double in 10 years. They're talking about Volkswagen Bluemotion, they're talking about Fiat Twinair. They're talking about fast charging and battery swaps and series hybrids. They're talking about folding bikes and multimodal commuting. They're talking about these things because they're being priced off the roads.
I have heard a middle-aged woman with no interest in cars or the environment say at a dinner party "I bought a Toyota iQ because it only emits 99g/km of CO2, so I don't have to pay road tax or the Congestion Charge.". For her, like many others, the efficiency of her car wasn't a side issue, but integral to whether she could afford to drive at all. Energy efficiency might not be on the agenda in the US, but it very much is in Europe.
