so now you have two insurances. two garages or live well enough to have two street parking. two maintenance bills. etc. etc.
I drive a four door sedan currently. It doesn't handle 100% of my motoring needs, that doesn't mean I need to own a moving van for that 0.1% of the time I need it. I just go rent it. It also isn't able to be checked as luggage when I travel, and so I rent a car when I arrive at my destination (if needed). I don't pay someone to transport the car to wherever I'm going.
This argument that EVs need to support 100% of all driving needs before they are acceptable is ridiculous. No vehicle handles 100% of driving needs.
My current car is a BMW M3, but I'm replacing it with a 530e (plugin hybrid). The 530e can't do everything the M3 could do from a performance standpoint, but it will be able to handle 80-90% of my driving needs in 100% electric mode. I'm 100% confident that my fiance's next car will be a pure electric vehicle (likely a next-gen Nissan Leaf or Chevy Bolt) that will handle 100% of her average daily driving needs. The only time we'll need to rent a car for her is when she needs to go on drives longer than 200 miles or so. That only happens 3 or 4 times a year, so we're not too worried about it as Enterprise will "pick us up."
m3 has such tight bearings that all it does outside of a track is break internal engine parts 80% earlier than any other consumer car.
now, even if you think renting a car that one time a month you need more than 100 miles, for most people it's a hassle they want to avoid more than you want to spend money.
and lastly, buying a new 530e will keep you carbon negative for two decades at least. not buying a new car is infinitely better than even buying electric.
So yeah, I used the performance features of the M3 on many occasions.
That being said, I live in Florida, and the car was, frankly, boring to drive on Florida roads. Driving fast in a straight line at speeds that won't result in my arrest aren't a stretch for the car, and driving the car at my limits makes me a threat to the safety of other people sharing the road with me when I find corners. There is a sweeping right hander on the Interstate off ramp near my house that I could take at 110 mph without the car, or me, breaking a sweat.
Moving on...
You might be right that renting a car once a month is a hassle for people. But I don't think most people go on 100+ mile drives every month (or at least average one trip like that each month).
And I always love how people talk about how much better it is for the environment it is to buy a used car rather than a new car, as if used cars just appear out of the ether. The people who buy my off-lease cars share in the carbon footprint of producing the car.
And even ignoring that, the lifetime carbon footprint of an EV, PHEV, or even just a non-plugin HEV is going to be lower than that of a ICE-only equivalent vehicle.
