Diesel Mechanic / HGV Technician (Mid-Level) vs Mobile Mechanic (Mid-Level)
How do Diesel Mechanic / HGV Technician (Mid-Level) and Mobile Mechanic (Mid-Level) compare on AI displacement risk? Diesel Mechanic / HGV Technician (Mid-Level) scores 67.4/100 (GREEN (Stable)) while Mobile Mechanic (Mid-Level) scores 65.4/100 (GREEN (Transforming)). Here's the full breakdown.
Diesel Mechanic / HGV Technician (Mid-Level): Commercial fleet diesel repair is anchored in unstructured physical work, DVSA licensing, and roadside breakdown environments that AI cannot reach. Safe for 5+ years with minimal daily workflow change.
Mobile Mechanic (Mid-Level): Core repair work is deeply physical in maximally unstructured environments — driveways, car parks, roadsides in all weather. AI-augmented diagnostics and admin are transforming workflow, but no robot can crawl under a car on a portable jack in a customer's driveway. Safe for 10+ years.

What Do These Scores Mean?
Each role is assessed using the AI Job Resistance Index (AIJRI), a composite score from 0 to 100 measuring how resistant a role is to AI displacement. The score is built from five dimensions: Task Resistance (how many core tasks can AI automate), Evidence Calibration (real-world adoption data), Barriers (regulatory, physical, and trust barriers protecting the role), Protective Principles (human-centric factors like empathy and judgement), and AI Growth Correlation (whether AI growth helps or hurts the role).
Roles scoring above 60 land in the Green Zone (AI-resistant), 40–60 in the Yellow Zone (needs adaptation), and below 40 in the Red Zone (high displacement risk). For full individual assessments, see the Diesel Mechanic / HGV Technician (Mid-Level) and Mobile Mechanic (Mid-Level) role pages.
