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.
> The normal failure mode of a carburetor leads to an engine that doesn't run, and not the opposite.
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.
> You can get a lot better efficiency from a carbureted engine than most people think.
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.
> As for safety, I'd rather have freedom.
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.
