Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
Can someone who is driving alone to work be considered to be in a form of khalwah (spiritual seclusion)?
Yes, this could be a lesser khalwah when one isolates oneself to be with Allah. It is like when someone wraps a shawl around their head so they can only see what is in front of them and not what is around them.
