How to handle unmatched riders?

[markusstraub]

Currently unmatched rider trips are teleported. Should we change this?

Previously we encountered the number of unmatched riders skyrocketing. Now that we got this under control with carpooling.riderMobilityGuaranteeMonetaryConstant this may be a non-issue.

The most logical idea is to replace the unmatched rider trip with the agent's original trip.

But there may be issues: We use subtourmodechoice to set the mode for all trips of a subtour to ride. Now if originally car was used for the whole subtour (e.g. consisting of 3 trips) we can not simply restore the car mode for a single trip if the other trips were matched - because the car won't be available

However: sbbrailraptor also ignores such situations, so maybe we could ignore it as well?
