EV drawbacks

Posted this in another thread but seems appropriate here as well...

EV drawbacks
 
And another report on local news of a woman and child becoming trapped inside their electric car,another tesla, when the auxiliary battery died. It operates doors, windows etc. Hot day, Temps were rising fast, child screaming. Dad was outside and could not get. It was quite while before they recalled the manual door pull. And where it was.
 
We need more warm weather not less


Findings
Across the 854 urban areas in Europe, we estimated an annual excess of 203 620 (empirical 95% CI 180 882–224 613) deaths attributed to cold and 20 173 (17 261–22 934) attributed to heat. These corresponded to age-standardised rates of 129 (empirical 95% CI 114–142) and 13 (11–14) deaths per 100 000 person-years. Results differed across Europe and age groups, with the highest effects in eastern European cities for both cold and heat.

What about winter temps effect on battery capacity. esp with heater/defroster in heavy use?

Seems to me kids toys have already solved the slow to recharge issue....when little Johnny's electric car runs down, he just gets Daddy to swap in freshly charge batteries and off he goes again. Surely a full scale vehicle could be engineered with a quick swap out battery setup? Just pull into a swap out station, car stops on an automated swap out device, battery tray is dropped out, freshly charged one lifted into place and away you go. The station would have a stack of batteries being charged around the clock.

Each battery pack weighing over a ton and change them just about every 200 miles, and what if the battery store burst into flames, and where's the power stations, coz the sun don't shine all the time and the wind don't blow at the optimum speed ?????

Seems this is a thing for motorcycles already....


Have heard Tesla did have a plan for this also, even previewed it on one of Musk's fancy tech talk presentations...but like many things he announces, nothing has come of it.
 
A Lancet study revealed that cold weather is responsible for approximately 90% of the 5.1 million annual excess deaths attributed to temperature.

If the cold causes 9 times more deaths than heat, would fewer people die if global temperatures were warmer?

OK, but I had a very similar issue with my 1990 BMW 535I. Doors auto locked; fuse blew, no manual door release inside the car. When my wife got home, she couldn't get out and I had never tried the emergency key opening method. Had her find the instructions in the manual and show me. Fortunately, I had read the manual when I got the car and knew there was a way and the spare key was in my pocket, so I was able to unlock the passenger door. The fun part once she was out and the problem was found and fixed is that all doors and the trunk were all un-synced and had to try the syncing procedure several time until I got it just right.

Good post because it reminds me that I need to figure out how to get out of my 2011 Mercedes E350 without power - never read that manual fully - it was my wife's car until she died.
 
Yes this underscores the very real risk of requiring vehicle operators to have knowledge of non-standard procedures. There will always be occupants in vehicles that do not know all the basic safety features of any given model. The door operating method was never an issue for decades of automotive history until makers starting implementing push button systems. Everyone knew how to open a door on any vehicle, all situations. Now we have various methods for different makers.
Sounds like a good case for standardization legislation.

It's not warmer that matters, it's runaway warming that matters. Since I'm neither far right or far left, the question for me is will runaway warming happen and I don't know the answer.

Something to think about: In the early 1970s the air in Washington DC metro area was not good and was terrible in Late July, August and early September. There is no industry in DC - it was mostly car pollution. The hated pollution controls on cars have resolved this and more. Today, you might see some car pollution in the air 2-3 days a year. Today, I can detect none. The population of the Washington DC Metro Area was about 2.5M in 1970 and is now about 5.5M so at least twice as many cars but almost no air pollution. However, the environmental warming by cars have increased due to more cars and they run hotter exhaust temps than in 1970. So heat the air much more but reduce the greenhouse gases - which wins? Don't know. Also in that time, US route 50 went from two lanes to 6 in most areas around DC - the asphalt makes the air temp about 15 degrees hotter (car reports 110 on a day when driving on a shady road reports 95). That road is 3072 miles long and a lot of it is four or more lanes wide - that's a good bit of extra man-made heat caused but using black asphalt rather than concrete (yes, I know concrete has its issues as well).
