Google Maps has introduced speedometer and speed limits on iOS and CarPlay more than five years after their debut on Android to help iPhone users avoid speed ticketing while driving. You can turn on the speedometer and speed limits by tapping your profile picture on the Google Maps app on your iPhone and going to Settings > Navigation > Driving options. Once enabled, the speed limits feature will change colors on the speed indicator to nudge you to drive within the speed limit set in your region. Is the Speedometer really helping to prevent accidents on the roads ?
