If I place the battery at the ambient temp, I’m sure it will get less time out of them.

As far as commuting goes, every one I know who owns one of these contraptions, plug it in their garage after they return home. Some of them have charging facility at their work (provided for free by their employers), they take advantage of those chargers.

Fast chargers are not terribly good for the battery in the long run and most of friends use them only when they absolutely have to… such as on trips that are longer than a couple of hundred miles. [In fact, only one person I know drove a Tesla from San Francisco to Chicago as an experiment and didn’t like the experience much.]

I think a hybrid is still the most practical option. A Prius is good and gives about 50-55 MPG. If one wishes for a little more comfort for longer drives, Lexus ES Hybrid is decent. [ A little worse MPG for extra comfort and features of convenience.]

The Bolt is one of the cheapest new cars you can buy period, is one of the most popular ride share cars, hertz has a butt load of them and rents then to ride share people, and best of all they have the slowest DC fast charging speed of about any car available( they are one of the worst offenders tying up dc fast chargers). I don't own an EV yet myself but this maybe the year since used prices are finally coming down to reality. I'm waiting to see what happens when most of the other makes gain access to Tesla's Super Charger network this year. I can charge for free at work, 120v at home till I get around to setting up a 240v option, and don't drive much day to day anyway.

It's big enough for hauling construction supplies, but it's not as convenient for hauling bikes as the Element. I'll eventually get a bike rack. I don't plan to buy any motor vehicles. Maybe in the next year or two, I'll get an e-bike.

Anyway, electric cars aren't for everyone, but it's working out well for us. The car is never inside. It's disappointing to see the battery drain when it's not even being driven, especially in the cold, but everything has its downsides and cost of doing business. I've heard maintenance costs on this car are not actually low: the tires are expensive, and she already damaged one and needed to replace it. I hear body work is super expensive. But fuel costs, even in the cold, are lower than a gas car. We have a hookup on our barn at our weekend house, so we "fill up" there cheaply. We have solar panels, so electric costs are quite low there. But that's 95 miles from our home in the City. She's found that Tesla Supercharger stations work well for her when she's en route somewhere, usually in New Jersey. I think they charge up to 40 cents per kwh. Charging in Manhattan is stupidly expensive for the energy, and they charge for parking, too. Lucky for my spouse that she doesn't need to charge in Manhattan.

Last night, we drove from the weekend house to our apartment in Manhattan. It was about 24ºF. We went from 91% charged to 46%, and that's worse than usual, but we can live with it since it's really not expensive. The battery is 75 kwh in theory. One cool thing is that when we plot the trip on the navigator, it estimates the amount of energy left in the battery at the end of the trip. It is extremely accurate. When we set off, it estimated 46%, and that' was exactly the result.

It might work a heck of a lot worse in lower temperatures.

Teslas are becoming viable for an increasing number of people, partly because of the extensive charging network. I see taxis in the City that are Teslas. Taxi drivers wouldn't be driving them if they didn't make economic sense.

Now with the Supernova M99 Pro DY light I have essentially a car headlight with high beam ability powered by my front wheel moving from my pedaling is there anything better? Granted the light isn't installed yet but soon will be

I use a lot of those for a variety of things. But rarely use them below freezing.

The light detected a drop in voltage and would shut itself off. The first fall, this started happening about 13 miles into a 23 mile commute on cooler mornings, like around freezing. The batteries would cool down and the voltage dropped, and the light thought they were out of juice. Fortunately, the light didn't like the cold either and died that winter. I moved onto lithium ion after that.

Notice the vague announcement from the company for having done some magical software updates to improve performance in winter. Does this mean that being in CA and TX they are so unaware of the range of temperatures where their EV will be used when it becomes ubiquitous, as they wish, that didn’t foresee this possibility and thought of “addressing this problem” only occurred to them after people were stuck with a dead car for multiple hours!

Hertz bought a large number of Tesla cars and they are apparently loosing money because of unexpectedly higher cost of repairs and maintenance.

In fact, if need something larger like a regular sized family car with large trunk, we have to specifically request a larger car or a Prius will show up. So far, I haven’t seen Tesla taxis here but that doesn’t mean they might not be there - I haven’t used a taxi for almost a year.
