currently there is only a tab for "My rides" that shows the rides and storage reserved by the user, I would like there to be two of those one that shows the rides and storage reserved by the user and one that shows the rides that are being given by the user or that the user has signed up to give

In my PHP app "Seat Saver" at /Users/louiseoconnell/Herd/seat-saver, there's currently a "My Rides" page (pages/my_rides.php) that only shows rides/storage the user has reserved as a passenger. I want this split into two views under "My Rides": one for rides the user is riding as a passenger (the existing view), and a new one for rides the user is driving/has offered to drive (created via the existing "Offer a ride" flow).

Let the driver see their upcoming offered rides — which event/car/time each one is for, who (if anyone) has reserved a seat or storage on it — and let them cancel a ride they're offering if they need to. Use whatever tab/sub-page structure fits naturally with the rest of the site's navigation and styling; keep it consistent with the existing look and feel rather than introducing a new design pattern.
