| Jan 29, 2021 at 3:56 | comment | added | cowboydan | @Flater Let me rephrase the question: are empty interface implementations a code smell? Or is it context dependent? | |
| Jan 29, 2021 at 2:06 | comment | added | Flater | [..] These are just some of many reasons why it's not that productive for two people to talk about their own interpretation of an unspecified requirement, because it's so very likely that things get lost in implicit translation. | |

[..] Additionally, there are real world considerations that change the design decision you might make. (a) Most automatics nowadays allow for tiptronic (i.e. human decision but automated shifting maneuver) (b) Does your code meaningfully distinguish between the implementation differences of a manual and automatic gearbox (i.e. the physical device, not the automatic gear shifter on top of it) (c) what about different automatic settings based on weather conditions? Do they affect shiftUp, or is the act of shifting a gear the same even though the decision at which RPM ro shift is different?

@cowboydan Your question in comments isn't meaningfully helpful. I mean that in the sense that you're asking about someone else's imaginary requirements about an already quite unspecified example with unknown requirements. But what Robert meant (correct me if I'm wrong) is that a shiftUp method would be largely the same in both an automatic and a manual car, as they both shift gears. It's more the decideToShiftUp logic that is different. This is why I mention that it's about imaginary requirements. You expect something completely different than Robert/me for what shiftUp would contain.

A manual transmission and an automatic transmission are both IShiftable. The difference is that one shifts automatically, while the other does not.
