  • Superficially, typing <Ctrl>+<left> seems to be the same as typing <Esc> <b>, but these are two completely different paradigms of using the editor.

    Vim does not use shortcuts or hotkeys to edit the text, it uses a language to communicate with the editor.

    For me, shortcuts and hotkeys are rote memorization, and I’m bad at rote memorization – compare your point “5. Ctrl-{ or } does this I think”. Do I need Ctrl-left, Super-left, Alt-left, Shift-left or Ctrl-Shift-left to jump back a word?

    The vim editing language is mostly consistent and logical. I did not need to memorize it, I could learn and understand it. But that’s just me.

    Far too much examples:

    Most commands are abbreviations – a for append, b for back, c for change, d for delete, e for end of word, f for forward, g for goto (and more), hjkl are special, i for insert, m for mark, n for next, o for open line, p for paste, q for reqord macro is a strange spelling, r for replace, s for substitute, t for to, u for undo, v for visual mode, w for word, x for extinguish, y for yank, z is just a prefix for arcane stuff. Capital letters are usually variants of their minuscle counterpart – like A for append at end of line.

    Commands take a repeat count, and a lot of commands take objects/movements, and these reuse the commands, like “delete inside backticks” => di`, “yank inside brackets” => yi{, “change up to third slash” => c3t/

    If you are fluent in vim, you won’t type shortcuts while editing, you will talk to your editor.

    As for more compelling examples:

    “I’d like to change the next 2 sentences” translates to )c2)

    “Please format this paragraph.” translates to gqap

    “Swap these two characters.” translates to xp

    And I did not touch ex mode, vimscript and plugins yet.








  • That’s fascinating. Especially the rain part, because our Tesla’s driving assistant just does not work in bad weather. I cannot imagine how it is technical possible to get a camera-based system to work reliably in bad weather without some mechanism to keep the cameras clean. Our rear camera is basically unusable during winter unless we get out of the car and clean it every single time we need it.

    Thank you for your advise!



  • That’s possible, I’m comparing what I know.

    By the way, VW hasn’t just a lane keeping tech, the car is able to drive autonomous in standard situations. Our VW (build 2022) was far better than our Tesla (build 2023) in lane detecting, lane keeping, reading traffic signs (dven in the Netherlands), navigation, detecting city and village boundaries, detecting crossroads, keeping distance and following lanes in curves – the tesla tends to ignore the law of physics and to go to fast. Tesla is far better at detecting waste bins though. It detects every single wastebin there is anywhere within 3 m of the road. VW lacks autonomous overtaking, and it slows for traffic lights but does not stop for them when they are red, that’s two points for the Tesla. Though Tesla slows for traffic lights even when they are green.

    The VW was able to drive home from work almost autonomous – there were two crossings, one traffic light and one roundabout it needed my assistance. The Tesla would crash multiple times.

    The most annoying thing with the Tesla is that it does not cooperate with the driver. VW has a genuine assistant – the car drives, and when I correct it, the VW just smoothly accepts the correction and carries on. The Tesla just stops working anytime the driver intervenes.




  • We’ve got an Tesla and an Volkswagen ID3. Tesla’s charging planning is pretty good. Volkswagen’s driving assistants are vastly superior to Tesla’s (despite not being oversold as “autonomous driving”).

    IIRC, the first robotaxis are operated by companies owned by Google and General Motors, and the only car that has a licence for fully autonomous driving in Germany (up to 60 km/h, only on Autobahn) is a Mercedes.

    No, Tesla’s autonomous driving is not cutting edge.
