I do not know what gasoline costs in Canada. Where my wife and I live that would currently by about 1000 gallons of gasoline. That would take a typical car about 25,000 miles. In the State of Washington the typical vehicle gets driven about 11,000 miles a year. So it would be improbable for an EV to save most people $4000 a year. EVs typically cost more to begin with and the batteries cost a lot, some up to $40,000 or more. And they typically last only about 10 years... depending on how well people treat them and how much the car is driven. It makes me wonder if they factored those types of expenses into the equation... not to mention the cost of electricity at charging stations and the inconvenience. This reminds me of a discussion that I had a few years ago with an elderly friend. He and his wife were on the second or third Prius Hybrid which is a far better solution for most people than an EV for most people. They had a three-year lease and got a new Prius every time the lease was done.
He was bragging about how much money he was saving by leasing the Prius Hybrid's. He said that he was averaging nearly 50mpg. The one he had at that time was two years into its 3-year lease. Then he said he had just taken it in for its second yearly maintenance checkup and the car needed no repairs at all! They were an older couple and drove approximately 200 miles a month or around 2,500 miles a year. In an entire year they used only about 50 gallons of gas in their Prius. At that time gasoline was around $2.50 a gallon. In two years, they had spent only about $250 for gasoline.
Then he bragged that the lease payment on their Prius was less than $500 a month. I didn't bother to point out that the lease payment on a much less expensive non-hybrid car would have been a lot less money. If he had leased a car that used 25mpg that was $10,000 cheaper, larger and more powerful, with the amount of driving that they did it would have cost them only $125 per year more for gasoline. This was probably about the same as the difference in the monthly lease payments.
So no, because they did not drive very much, the Prius was costing them far more than if they had purchased a cheaper non-hybrid vehicle. But both he and his wife were virtue signalers to the max and the Prius and it's lower “carbon footprint” made them feel very good. So maybe it was worth it for them.
“...he and his wife were virtue signalers to the max...”
I know a few like these. They are not alone.................
“But they drove with pride.”
A current ballpark figure is about $6 per gallon Canadian or about $4.5 US for regular.
