Transport and vehicle perspective
Choose ехать or ездить from the motion event, not from public/private transport.
Ехать describes one directed journey by transport. Ездить describes habitual, multidirectional, or there-and-back travel.
- Vehicle ownership is irrelevant.
- Current directed journey favours ехать.
- Habitual or completed visit-and-return favours ездить.
