The clinical name for driving phobia is not Drive-o-phobia.
In fact there is no recognized clinical name for a phobia of driving. Which is quite an omission for such a common phobia.
Some therapists refer to the fear of driving as Hodophobia but that is far too general as it is defined as a fear of travelling (from the Greek word Hodo meaning: going, movement, travelling). This is a very different thing from a driving phobia which attaches specifically to driving and often to very specific driving situations.
