Either way, if you've had a fuel injected car you were still exposed to these issues. You would have to go buy a carbureted engine from the 80s or before to get away from these "unintended acceleration" issues, as in the end a car with EFI probably has a computer actually controlling the injection.

Even with EFI, if the throttle is mechanical and the EFI continues to ask for more fuel for whatever reason (or a fuel injector gets stuck open), all that will happen is the engine will stall due to the excessively rich mixture.

Ever have vacuum hoses fail on an old car? Carburetors get stuck or clogged?

The normal failure mode of a carburetor leads to an engine that doesn't run, and not the opposite. Before complete failure, you will notice a performance decline.

Personally, I prefer no computer control.

On top of that I'll also get much better efficiency and reduce harmful emissions which hurt my family and my neighbors

You can get a lot better efficiency from a carbureted engine than most people think.

As for safety, I'd rather have freedom.

If the throttle is mechanical. So yeah, I guess there's a window of time there where EFI became the norm but before throttles were also electronic, so late 80s to early 2000s. I imagine the majority of cars on the road today in the US are fully electronic.

I've personally experienced carburetors getting stuck open, usually on abused/unmaintained lawn equipment. I do agree the usual failure is that it gets gummed up and inefficient in its atomization, but a stuck open carb isn't impossible. Either way, a carb that fails and you suddenly lose power can also cause problems when unexpected.

Yeah, a well-tuned and well-maintained carburetor isn't absolutely horrific in efficiency. But it'll still pale in comparison to the combustion efficiency that can be had in a GDI engine.

Cool, and feel free to drive that freedom car in your freedom yard. Please keep your freedom emissions in your freedom air though instead of polluting your neighbors. When you're driving on the public streets there's more than just you out there.

Freedom includes doing things that others don't like --- and tolerating the opposite too. Otherwise you're just encouraging an authoritarian socialist dystopia.

So I should tolerate people driving on public streets without insurance and without a license? I should tolerate people driving the wrong way on the highway? I should tolerate whatever emissions come from the tailpipe of someone's car? I should tolerate sompeone driving a car that nobody has touched the brakes on for a decade and they're about ready to fail at any moment? I should tolerate people driving at night without headlights on? I should tolerate people driving at any blood alcohol level?

All of these are laws which limit freedom in the name of safety. You're arguing you'd prefer freedom over safety. Personally, I prefer all of these tradeoffs of freedom over safety, at least when driving on public streets. If you don't like these regulations, don't drive on public streets.

Requiring a driver's license, having emissions controls, creating traffic standards for driving on public streets are examples authoritarian socialist dystopia I guess.

As far as I have understood, the previous commenter used to talk about FLOSS only (which is rather wise then not if you do value RMS' philosophy) and you have turned the discussion into absurd (kind of driving without license which has nothing to do with wiseness).
To me they brought it to that extreme when referencing authoritarian socialist dystopia when originally talking about carburetors. Hard to not see it going that direction about rights/freedoms when not having the ability to tune your carb means you're encouraging an authoritarian socialist dystopia.
It has been meant that there is no any car with FLOSS injector software. Every injector hardware devise has proprietary software. How on Earth can I drive an injector car if any proprietary software is not an option for me?
Carbureted engines are significantly less fuel efficient than modern engines that use fuel injection systems. They're less precise; often times not able to fully burn all the fuel supplied.
