We’ve always shared. When we lived a fair distance from the train station I used to get up early and drop DH, then collect him in the evening. We have now moved and chose to live in a village with a station, so DH now walks to and from his commute. We are also walkable to school etc. We occasionally have clashes, but work round them, and if DH goes away for the odd weekend, we usually hire a car if needed. That works out much cheaper than running a second full time.
