I drive to and from sessions often because I am coming from work. I've only had one session where I left very upset and drove home in the dark with only my running lights. I drive 25 minutes through the countryside to get home. It scared me enough to know that if I can't drive I should just sit in the parking lot for awhile. But in general, my t does a good job of wrapping up at the end of session so I am not left with the emotions unpacked when I leave.
