my Garmin radar stopped working when it was around 19 degrees. the battery was Fien it shut did not work. I wondered it I had it in the house and brought it out it would be ok?

When I buy an item I plan to use on a bike, one of the first things I do is throw it in the freezer. A built-in battery might quit working, or the display might become unreadable. I had tire levers made of steel coated with plastic. The plastic peeled off in the cold - no kidding. When things like that happen, I can still return the item, and I do not eventually get left in the cold.

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

I didn't thoroughly read through all the posts, so forgive me if you got your question answered. I ran NiMH batteries in a light maybe twenty years ago. 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.

It's bad when the legal system lets a lot of the issues slip thru the cracks, & then ends up dealing with a much larger problem later on down the 'road' .

I am assuming bad refers to how it affects people. Laws are made by politicians, majority of whom are not exactly honest people. So from their perspective, it’s actually good - more opportunities to make more money by arm-twisting and settlements (lawyers) - no admission of guilt, it all works quite nicely. :sad:

These systems in the us are supposedly developed & driven by the "people", yet here we are...

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.

That's weird. In the NYC area, including the suburbs, you normally get something that is grossly oversized such as a maximum-size SUV. I believe the thinking is, "I'm paying so why should I get a ride in anything downscale?" What a horrific waste!

In 2016 on my first airplane trip with my S&S coupled bike in a S&S case that is 26 X 26 X 10, plus a second checked bag, I called my normal taxi company and asked if my luggage would fit in one of their Prius taxis. They were not sure, suggested I call a different taxi company, they did not want to risk being the reason I missed a flight. So, I called one that drove mini-vans. He shows up with a Prius. My luggage did fit in the Prius just fine, but I asked where the mini vans went. He said they were selling off the mini-vans and buying Prius cars. That was the two biggest taxi companies in my community, both using Prius taxis.

During covid, one of them switched to Teslas, and then went out of business, but I have not needed a cab since covid started, so I am not sure who is driving what now.
