This is the "message" that Tesla needs to convey when Model 3 arrives because at its price point the gas and maintenance costs will make a huge contribution to the total cost of ownership. Model S's TCO is harder to swallow because of the higher point of entry price wise. To me Model S at the moment is still about the mission to prove that EVs are better in every way by blowing the doors off ICE vehicles with performance. That's what gets the media attention despite their OCD focus on its purchase cost.
Funny, Tesla's been trying to say how much it costs per month with gas savings, and people have been complaining. However, I really don't think that manufacturers will have a problem shifting 200-rated BEVs at $35k, as long as they are BEV-peppy with <= 7s 0-60, especially in countries with high gas prices, and that includes cars that'd rely on slow-fast DC chargers. I really, truly believe that there's pent-up demand waiting for the cars. And I think that Toyota's going to be staring down the barrel of a gun. People didn't trust hybrids and within 10 years consideration had reached 80%. Same will happen with long-range BEV, and growth potential is higher than hybrid because the overall experience is better.
