You are correct the degrade of a battery over time is a factor but ev tech is fueling hybrid tech. the miles per gallon is getting better on the hybrids especially the plug in hybrids. The different style driving should dictate the choices made by the end user. Multiple car = ev / short commute = plug in hybrid / lots of miles on the commute or irregular intervals where charging stations are full or unavalible= reg hybrid / if you tow you need a truck just no way around that oneMy real argument is about the long term cost of ownership. If you bought a long range Tesla 3 and a similar equipped Toyota Camry the initial purchase price difference is $13000. The Tesla will break even at around 7 years if your drive 14k a year. Problem is that between year 10-15 you’re going to need to replace the Tesla battery. This will currently cost $13k. That basically starts the clock over. In the long term you won’t save very much money. You may end up paying more because the resell value on an e/v is going to always be worse dir to the nature of its battery degradation.
The key is if you plan on driving a ton with an e/v. This may be a problem due to the current fast charger infrastructure and availability. This is where I think a stop gap comes into play. Hence why Toyota is sticking with hybrid technology. You’re really getting the best of both worlds with battery’s that cost a fraction of an e/v’s battery pack. My Prius V still gets 44’miles a gallon and she’s 11 years old. Battery replacement cost is 3k. The new Prius’s get around 60 miles per gallon and I would expect their batteries to be of even higher more long lasting quality.
