> How would it feel if there was data about a crash you were involved in that you could not get access to? I'd be angry that data was recorded in the first place. No data should be recorded without the driver's explicit consent.

Ya I dunno. In the USA driving is a privilege, not a Right.

Using the restroom at Starbucks is a privilege, not a right. That doesn't mean I expect to be recorded in the restroom.

old vehicles are very inefficient in terms of safety, fuel consumption, and exhaust gases, for this reason alone one should prefer electric or modern era ICE

The emissions cost of building a new car and shipping it halfway across the world will significantly affect this calculation. You can drive a less efficient car for many years on the carbon cost of building a new one, as long as you're not driving some huge pick up or other obscene gas guzzler.

The second part of what you said is a widespread myth.

There is a crossover point after you drive a certain number of miles in an EV, after which the lifetime carbon cost is lower than that of an equivalent ICE car.

For Model 3 the crossover point is estimated at around 5,000 miles. Not "many years."

The sources and methodology for this estimate are discussed in detail in Tesla's 2020 Impact Report.

Excerpt:

Variables often overlooked by other lifecycle studies:

* Using Worldwide Harmonized Light Vehicle Test Procedure (WLTP) or Environmental Protection Agency (EPA) fuel/energy consumption data (both of which overestimate fuel-economy and underestimate emissions) rather than real-world data;

* Not considering the higher energy efficiency of Tesla’s powertrains;

* Assuming the average EV needs a battery replacement at some point in its life;

* Not considering emissions generated through the oil refining and the transportation process; and

* Using outdated data for the carbon impact of cell manufacturing.

My 2013 car is not particularly laden with gizmos and has been very easy to repair (no real breakdowns...).

It depends a lot on the car and the engine. If you want a high-performance engine that meets modern emissions requirements, you're probably going to be looking at EFI and turbochargers. Changing the fuel injection maps on a modern car requires something akin to rooting/flashing an Android.

EFI is pretty much all upside though. When things do go wrong, the engine just tells you what the problem is.

Disclaimer: I work for a Tesla competitor. To combat fundamental attribution error, whenever you read an article about Tesla, try replacing the word 'Tesla' with your least favorite car or consumer product company. 'Brand X' has a bunch of data about accidents, and they are motivated to not share all of it with authorities. When they do share data they are motivated to share the data that presents them in the best li…

Sorry to be a pendant, but disclosure, not disclaimer.

While Tesla knows more info about how you use or operate the car, the big piece that matters to your privacy is arguable the vehicle location and that is not at all unique to Tesla. Many (most?) vehicles produced in the last decade have a GSM modem that pretty much continuously leaks your data at least to the cellular networks, and likely the vehicle manufacturer/operator. I used to physically remove the modem from m…

Why did you stop if you 'used' to do it?

I like this youtube video that goes over various crossover points. The tesla beats the RAV4 prime at ~45k miles and a rav4 ICE at ~28k miles: https://www.youtube.com/watch?v=MEqxaH47DTs

I think 5k miles is a bit low, and using tesla as your only source biased.

Are there any current or upcoming electric four wheel vehicles that aren't a privacy nightmare?

Unfortunately, the new gas vehicles being sold today are also privacy nightmares, just look closely.

I think the point is that there's plenty of older "non-connected" vehicles, but they're not EVs. If you want an EV it will have to be a newer one.

(Obviously I'm excluding all the non-street-legal "EVs" like golf carts and the like, as well as the truly antique and rare EVs that did exist around a century ago: https://en.wikipedia.org/wiki/Category:Electric_vehicles_int... )

I've definitely been hesitant to buy a Tesla for exactly this reason. It's not clear if you can turn it off or avoid it by not using FSD either. It's a shame, would love to own one some day. But I'm guessing the option of buying a car that doesn't have this is slowly dying unfortunately. Consumers never win with this sort of stuff. The really ironic thing is that it is tied in with a more environmentally friendly car…

The really ironic thing is that it is tied in with a more environmentally friendly car. Want to avoid being spied on? Then you need to use dirty fossil fuels.

I see similar parallels with software. Want a sane UI with the functionality you need, or avoid being spied on? Then you have to use "insecure" older software.

I will continue to repair my ‘70s and ‘80s era vehicles, because newer models that incorporate electronics are all total garbage. Reason: embedded engineer for 30 years who has worked on automotive software.

Some people care more about other things when choosing a vehicle. I suspect motorcyclists are far less worried about safety, for example. Performance enthusiasts too, although not to the same extent; and some just want a comfortable roomy ride with plenty of power as well as ease of repair and parts availability.

As the saying goes: "It's not about the miles per gallon, it's about the smiles per gallon."
