Sometimes you'll have a user in your matches whose route isn't as close as you'd like. You can 'Disconnect' from these users to free up space for other riders.
If you don't want to interact with a certain user anymore, just tap on their profile, then tap the 'Connected' icon and this will ask you to confirm whether you want to disconnect or not. It's that simple!
Please note you won't be able to reconnect with them once you have done this.air
