What does Speedometer show on the CarPlay screen?

Speedometer's CarPlay view is designed for one job: glanceable driving data, optimized for the car. You'll see your real-time GPS speed in large, high-contrast type, plus current trip stats (distance, duration, average and max speed) when a trip is active. Layouts follow Apple's CarPlay design system so everything stays readable at speed and switches between day and night modes automatically with the rest of CarPlay.
