You're missing the fact that an electric car is just electric motors and a battery in a car as well. Those are exceedingly simple to install in other cars and many conversions are happening with tesla motors for example.

There is no difference. The software is what controls the cars nowadays. Single massive screens are in virtually every car now. There is nothing about being electric that makes cars more or less hackable.

Not really.

I have a modern gas car and a modern ev, and they are comparable on this point. The telematics are invasive and have been the path for "recalls" on both vehicles.

The main difference is that the gas car does implement a legally mandated standard for diagnostics, but only for things that cannot be wrong with ev (only facets pertaining to hydrocarbon emissions). If the gas car has a problem not related to emissions, it's proprietary diagnostics.

Once upon a time some vendors just concentrated all their stuff into a double din you could rip and replace. Then you have some with the standard form factor, but you needed to somehow keep a proprietary module in the mix or else a bunch of the car wouldn't work. At this point, it's generally a lost cause to even think about rip and replace of the head unit for most cars less than 10 years old.

Some folks like in a gas car they can visually see the belts and components like alternators and do their own oil changes and air filter changes while the evs generally have things more tucked out of sight. However they don't really have analogous sorts of failures, so you would not have engine air filter, oil to change, nor any belts or associated tensioners, so it's just replacing easily serviced components with strategies that are more robust.

You can have EVs have obnoxious components fail that are a pain to replace, but gas cars generally have the same stuff too and those are also tucked out of the way. Saw a video recently of one model where changing the timing belt required the mechanic to basically take apart most of the car, due to various obnoxious clearances.

How high are you right meow?

You don't like electric cars because of a thing that is also in modern ICE cars, and the difference is that it's a thing you don't understand so you believe it's worse on electric cars?
