Some carpoolers have flexible schedules, but others need to leave at a fixed time. To avoid receiving suggestions that don’t fit your constraints, you can set your exact departure time and your level of flexibility (up to 45 minutes before or after your chosen time).
How to do it?
Go to Account > My usual trip > Schedule
For each day of the week, select your departure time and your preferred flexibility.
This way, you’ll only get ride suggestions that match your availability!
