Sure, for professional racing drivers.

The vast majority, certainly >90%, of people who claim to be driving more efficiently manually are simply mistaken.

It's mostly observation bias. They recognize those two situations a day where they really have the upper hand. For a second or two. They don't realize that in most other driving situations they don't even come close.

Racing divers would shift exactly like automatic because they need to tease the best possible acceleration out of a given engine configuration.

Day to day driving is wildly different from that, there are only very few situations where people come anywhere close to the maximum acceleration their car would offer. With manual transmission, you can attain submaximal acceleration by flooring the throttle in a low gear. This is much more fuel efficient than getting the same amount of acceleration with a throttled engine at higher rpm. Automatic transmissions make that more difficult or even impossible (depending on implementation).

Worst case: people are unhappy with the acceleration they can get at low rev, because the transmission only allows low rev at throttled state and they don't consider it socially acceptable to rev up. The engine would be capable of much more torque at the desired rpm, if only the throttle could be opened without the transmission shifting for higher rpm. Next time they will get a bigger engine that will be throttled even more. ICE inefficiency rises with high rpm and closed throttle (opening the throttle raises power output more than consumption). Ideal ICE efficiency is when the gear is selected so that torque at open throttle matches the power demand. Manual can come much closer to that than automatic. (Unfortunately, many people don't know that and drive manuals like automatic, e.g. never at really low rpm, never at really open throttle, because they think that opening the throttle would be wasteful)

I'm not going to say "you're wrong" but I think there are plenty of situations where you know or can anticipate what gear you need to tackle a certain scenario, where an auto simply can't know.

For example, a set of 90 degree bends with (very) short straights between them (this is a real scenario where I live and why I've thought about this at length already). In a manual, you might ride the entire set of bends out in a low gear so you get both the most acceleration between bends and not have any gear changes mid-bend so you're ready to accelerate out quickly. An automatic, on the other hand, would be inclined to change up gear between bends and then have to change back down again once you want to accelerate out as it wouldn't really know what was going on.

My car's transmission has a wide variety of options, including a "race" mode, and I usually drive manual instead, because the semi-automatic options seem to be terrible at anticipating anything and coaxing them through throttle alone is an art beyond me.

I know what you mean, the similarity between an automatic and a race driver was only meant to be about the specific context of fuel efficiency, not about shaving of a few more second from your lap times. But in the end, both of those wildly different optimization goals can benefit from a driver's superior ability to anticipate future power demand. And both goals create comparable challenges in "coaxing them through throttle alone", which describes my frustration with automatics pretty well. In day to day driving, people seem to want a certain amount of acceleration at non-aggressive rpm, and automatics that make it hard or even impossible to tap the full low-rev torque of a given engine make people buy bigger engines than they would need if the transmission would better support their use case.

Give me an automatic that allows me to apply unrestricted (by backshifting) torque at any rpm and I would look at it much more favorable.

But note that the transmission in F1 cars is semi-automatic [1]

The only "automatic" part of that transmission is the clutch. The driver still has to select the gear, and I think that's what the whole discussion here about manual vs. automatic is focusing on.

They drive to the beeps, so the computer is beeping in their ear when it is time to change. And they don't shift through neutral to select a gear. They may as well be automatic for all the input an F1 driver has

The computer beeping is merely a reminder and I'm betting most drivers will even disregard it after they are familiar with the track they are on. Gear changes happen so often and so quickly that waiting for a computer to tell you when to shift is a sure sign of unfamiliarity with the track layout and it's also a hit to one's concentration (ex. if they're trying to pass the car ahead or block the one behind). Anyone that does any sort of track driving consistently should know what gear their car should be in for each corner long before a race.

I'm not sure I agree, if they served no purpose the engineers would remove them. I think when they are in 'lift and coast' the gear changes are different, and I'd guess when they turn the engine modes up they would change again.

If there is no dry clutch and no clutch pedal, I consider that to be an automatic. And in such a system, I'm only allowed to signal gear selection: if I make a mistake or request a gear someone else thought I shouldn't request, the software won't comply. This implies that someone is assuming they know better than me how to drive, and enforce this assumption. This notion infuriates me. It's one thing to operate within mechanical / physical limits of the system, and quite another were someone who is not me forces arbitrary limitations. I take the "we know better than you" extremely personally.

I suggest handling TCP packet retransmission yourself as well. Nothing beats having precise control over reliable data delivery.

Grin. But seriously, at some point, it simply becomes a question of low level control vs improved high level functioning. I love manuals, and drive one, but the writing is clearly on the wall for good reasons. Fortunately, buying a hybrid forces the issue anyway, as others have noted.

I used to code intros in assembler on the Amiga, and did some assembler on UltraSPARC, so the joke is completely lost on me. I love assembler and low level control.

You get mad because your assumptions about your own superiority get placed under doubt by reality and physics? Must be hell of a way to live.

Sounds like a dunning-kruger effect and some anger management issues rolled into one.

Now you're incorrectly assuming that the engineers' and programmers' assumptions about how I drive are correct, and they know better than me. Who are they and what do they know? Who am I and what do I know? What if I'm a professional driver or an engineer just like them, or both? You don't know either of the two parties, so how could you possibly judge this correctly? The answer is - you cannot. You are berating me for challenging what you perceive to be an authority, as if I hadn't studied physics and mechanical engineering and knew nothing about those subjects, and even go so far as to imply I'm incompetent and suffer from an illusory superiority complex based on Dunning-Kruger research.

Is this what we're coming down to nowadays, if someone says "I know what I'm doing, and I don't want someone else to tell me how to do it", they'll be sticker-slapped with a superiority complex? That's the society you want to live in? And that is okay?

Bottom line is: a car with an automatic transmission does not do what I want, how I want, when I want it, and does not drive the way I want and expect it to drive. It fails my requirements, whereas a manual transmission and a dry clutch don't try to meet my requirements or expectations - what I want, how I want it, and when I want it is solely up to me. If I mess up, that's on me as well. It's my problem, my responsibility, and that's great.

As far as I'm concerned, since driving is a very important part of my life and identity, dictating, through the use of transmission or shift points, for example, is attempting to dictate how I live. I, an individual, equate that with someone telling me what I must believe, and what I must accept, "because it's better for me", and this goes against what I believe is my basic right to self-determination. That is one of the reasons I reject the automatic. If I have no direct say in it, then at least I can indirectly vote with my wallet.

Must be hell of a way to live.

I deal with it.

Nitpick, but F1 cars do have clutches and they can be operated manually (and must be for starting). The big difference is the cars don't have a clutch pedal, but a pair of clutch buttons.

Now DCTs in road-going cars: undeniably automatics.

What does a dry clutch have to do with it? Wet clutches can be user controlled mechanical systems too, just look at the vast majority of motorcycles.
