The speed trace tells the story. Norris was carrying more speed into the slow corners and getting on the power earlier on exit. That's not driver skill — that's car performance. Hamilton wasn't making mistakes. He wasn't locked into a bad strategy. He was driving a car that couldn't rotate through Miami's tight sections the way the McLaren could.
By Lap 19, the gap was 21.7 seconds. That's not Norris pulling away late — that's compounding. Every lap, Hamilton lost six tenths in Sector 1, made up a tenth in Sector 3, and finished half a second down. Multiply that over 19 laps and you get a result that looks like a thrashing but was really just inevitable maths.
