> We really need to get serious about improving our transportation infrastructure. Better yet, we really need to consider urbanization. That way everything you need is right there by your own two feet. No need for any extra special transportation at all. It seems people have a burning desire to live the rural lifestyle, though, even in so-called cities. I'm not sure we can actually overcome that pressure.

Even with heavy urbanization you'll need some form of transit on top of walking. Have you ever visited any really big cities (eg. Tokyo)? Every time I'm in one, I get the impression they would grind to a standstill without their mass transit systems.

Even a decent town puts most things within a walk or bike ride. San Luis Obispo comes to mind as an example.

I suspect the biggest factor is speed. After getting used to EV for over a year, every ICE vehicle feels painfully sluggish and slow. If that's the case I'm curious to see how the numbers compare to other EVs.

You don't do much towing, do you?

How much data does Tesla have on the details of crashes? Probably depends on whether enough electronics survived to phone home.

It's possible to dig the airbag controller out of the wreckage and read out the last 30 seconds or so. Airbag controllers have a short but nonvolatile memory and usually survive crashes. That gets you speed, acceleration in several axes, plus steering, brake, and power inputs, and detailed info about what the airbag system did.[1] Those were originally created to tune the airbag algorithm, and, over the years, false airbag deployments have dropped almost to zero.

That's the basic info needed to analyze fatal crashes. Speed at collision? Speed 10 secs before collision? Accelerator and brake inputs? Maneuvering (side accel) before crash? That, plus the crash scene, tells most of what you need to know.

Law enforcement will sometimes read out those units, when it's not clear what happened. It's not done routinely.

I wonder how much of this is because (IME anyway) Tesla drivers are not very good. With all that tech it's easy to get distracted (there's literally a giant tablet looking thing for a console). It's also easy to think all the bells and whistles will do things for you so drivers are paying less attention because the car will beep and holler at them if things are going awry (except by that point it's too late).

Tesla drivers are young men with big wallets, stereotypically. That demographic is not known for their carefulness in traffic, or in any other matter. I'm sure that simple confounding factor is enough to explain the excessive fatality rate of Tesla cars.

> The study was conducted on model year 2018–2022 vehicles, and focused on crashes between 2017 and 2022 that resulted in occupant fatalities. Teslas can go fast real fast, so naively this is the result I would expect given how they have filtered the data. In other words, unless they controlled for this, this would be biased by natural selection playing out. Having said that, as someone who had a couple of close call…

Explain to me why you would want to filter out fatalities caused by going “real fast”?

In a big picture, this makes sense. You can load the cars with safety features, but it doesn't change the fact that these cars are very heavy, very fast, and loaded with features that reward distracted driving. In the US at least, the top killer of drivers are trees on the side of the road.

Aside from the distracted driving part, which is real, there are two physical aspects of the model 3 that I find to be safety issues as well-- the two front windshield beams are thick and add a sort of blind spot, and the side mirrors don't give you great field of view.

Same with my older Toyota. They stuffed airbags in them, which is nice, but I've had several times where an adult on a bike is completely obscured, with my passenger having to scream "stop!". After the second time, I now bob my head like a maniac to look around them.

Can't wait for displays on pillars, to make them appear transparent.

I would wager that most people don’t want to use public transit regularly. I know I certainly don’t.

Your desire to not be inconvenienced is not as important as the lives of other people who are being killed unnecessarily for it. That being said, to be clear, I don't think we need to make driving illegal or whatever. I think a TON of people would happily not be saddled with the expense of owning a car or the task of driving if there were reasonable alternatives on offer, which in the few pockets of the US that actua…

That said, I drove into a nearby city after dark which is increasingly early last night. There are no reasonable alternatives--I will for a 9-5 event but just doesn't work for the evening. There's a decent mass transit system including commuter rail but it it's just not organized around coming in at 5pm. It's chaos with cars/cycles/escooters/pedestrians often randomly crossing streets, poor visibility, etc. I mostly just don't go in any longer.
