Mercedes-Benz commits to bringing back physical buttons

Original Article ↗ Hacker News Discussion ↗

Mercedes-Benz’s plan to reintroduce physical buttons in future models is being welcomed as a reversal of the trend toward screen-only car interiors. Commenters argue that touchscreens and capacitive controls are often unsafe and frustrating to use while driving, citing poor ergonomics, aging users, gloves, and laggy software, and note that regulators in Europe and China are starting to push back by requiring hardware controls for key functions. The move is also framed against broader industry pressures: traditional automakers trying to emulate Tesla’s minimalist, software-heavy approach, cost-cutting via fewer mechanical parts, and fears that weak UX and tech strategy leave European brands vulnerable to Chinese EV competition.

Buttons vs touchscreens & safety

  • Strong support for returning to physical buttons, especially for climate, media, and driving-critical functions.
  • Main arguments: tactile operation without looking, works with gloves / cold / dry or aging hands, less eyes-off-road time, less night glare and visual clutter.
  • Touchscreens criticized for:
    • Missed taps, fat-fingering on bumps, and gesture vs tap ambiguity.
    • Modality and deep menus (function depends on prior state, multiple layers).
    • Changing layouts after software updates.
  • Some praise good mixed setups (e.g., physical knobs + screen for optional features) and cite specific older German and Japanese models as “near perfect”.

Regulation, China, and motives

  • Several suspect Mercedes is reacting less to “learning” and more to:
    • Reported upcoming Chinese rules mandating physical buttons for key functions.
    • Euro NCAP changes tying 5‑star ratings to physical controls for common operations.
  • Debate over China’s broader regulatory role: some see a positive “Beijing regulatory effect” similar to Brussels/California; others point to human rights and geopolitical issues.

Software, UX, and automakers

  • Many say German brands historically excelled in mechanical quality but have fallen behind in software/UX.
  • Critiques: laggy, buggy interfaces; over-complicated, committee-designed systems; CARIAD held up as a “trainwreck”.
  • Others defend recent VW/BMW systems (e.g., ID.3, iDrive 8.5) as now quite good, and note Apple CarPlay / Android Auto support.
  • Broader view: European industry strong in hardware, weak in pure software and consumer UX.

Tesla and screen‑only designs

  • Split views:
    • Fans: Tesla UI considered responsive and well-organized; voice commands and automation (auto gear select, climate) reduce need for physical controls.
    • Critics: still forces eyes off road; essential actions (gear, fog lights, wipers) can be multi-step; rental experiences especially bad; safety concerns over door handles, stalk removal, and ADAS quirks.

Cost-cutting and incentives

  • Widespread belief that screens are primarily a cost‑cutting and flexibility measure:
    • Fewer unique parts, easier parallel development, OTA feature updates, and cheaper BOM.
    • Even tiny per‑part savings scaled over millions of cars drive decisions.
  • Some point out low-cost brands still manage extensive physical controls, implying design choices, not inevitability.

Broader reflections

  • Many see touch-everything as part of broader “enshittification” and “phone-brain” product thinking invading safety‑critical machines.
  • Desire from some for simpler, minimally computerized cars with direct mechanical controls and little or no connectivity.
