I fought against tech for a long time, thinking it made mechanics lazy. Seeing how FAST it finds issues changed my whole view.
Cleaning the ground connection fixed the flickering light.
A customer's older sedan came in with a cracked manifold, and every bolt was rusted tight. I used heat and penetrating oil for hours on Saturday just to loosen a few. By Sunday night, I was still extracting the last one with a drill. Why do people think complex fixes can be done in a snap when rust and age don't care about your schedule?
