Piotr Klarowski Publishes ‘Designing for ADAS’ Playbook: Safety, Usability and Validation Methods for In-Vehicle UX
London — October 27, 2025 — Piotr Klarowski, a senior product designer specialising in automotive UX and human–machine interfaces (HMI), today released “Designing for ADAS: A Playbook for Safety, Usability and Validation”, a practical guide that distils more than a decade of design practice and public thinking into actionable methods for teams building advanced driver assistance systems (ADAS) and in-vehicle interfaces.
The playbook consolidates frameworks and lessons drawn from Klarowski’s work with both high-velocity startups and major OEM organisations — including design work at Arrival and Toyota’s Advanced UX (Woven by Toyota) as well as his public writing and talks on in-car UX, ADAS, and connectivity. It brings together the principles outlined in his medium essays (notably “Sketch to Dashboard” and “The Role of UX in ADAS and Automated Parking Systems”), his public speaking on connected mobility, and practical process guidance for moving ideas from sketch to production-ready dashboards.
“As vehicles become software-defined and ADAS features proliferate, design teams need clear, testable workflows that prioritise user safety while allowing room for innovation,” says Piotr Klarowski. “This playbook is intended as a field guide: exercises, test protocols, and decision checkpoints that help translate early concepts into validated, deployment-ready HMI.” (For review/approval: direct quote supplied by author.)
What the Playbook Contains
• A Practiced Pipeline: A step-by-step pipeline that mirrors Klarowski’s ‘Sketch → Research → Prototype → Integrate → Iterate’ approach, emphasising low-fi sketching and rapid validation up front, followed by multi-fidelity prototyping and system integration for production contexts. This approach is informed by his published process thinking and industry experience.
• Safety & Handover Protocols: Concrete methods for designing and testing handovers between human drivers and automation, including multimodal feedback strategies (visual, auditory, haptic), clear state signalling, and progressive disclosure patterns that reduce cognitive load during transitions. These protocols expand on themes from Klarowski’s writing about ADAS and automated parking.
• Validation Playbooks: Field-test and simulation templates for validating ADAS interactions under realistic conditions — including network degradation, sensor noise, and edge-case scenarios — reflecting Klarowski’s emphasis on research-led design and safety validation common in OEM environments.
• System & Ecosystem Thinking: Guidance on treating dashboards and HMIs as nodes in a broader mobility system — accounting for cloud services, charging infrastructure, fleet management, and companion apps — so that interface decisions reflect operational realities and sustainability goals. This section synthesises Klarowski’s system-level perspective observed across his public talks and projects.
• Resilience & Privacy Best Practices: Design patterns for graceful degradation when connectivity or sensor data is intermittent, and straightforward privacy controls that let users understand and manage data shared for predictive or connected features. These are consistent with Klarowski’s public emphasis on resilient, human-centred connected systems.
Why This Matters Now
The industry is rapidly moving toward software-defined vehicles and ever more capable ADAS suites. Klarowski’s playbook arrives at a moment when design and engineering teams must balance speed with the rigor required for safety-critical systems. By providing repeatable processes and templates for validation, the playbook aims to reduce risk, speed up credible iteration, and improve the quality of in-vehicle experiences delivered to drivers and passengers.
