@ Diandra - That's a fear based in social anxiety and effects over 25 million Americans. I wrote a
long post on that one a few months ago.
@ moonrambler - Yep, that sounds like a phobia. The fast phobia cure if done properly should help with that.
@ gigi - Bridges is another common one so not that weird ;-) People that have that fear nearly always talk about driving over bridges. I usually encourage them to drive 'on' then rather than over them. The language is crucial.
@ coppercoin - That's classic social anxiety and probably not a phobia per se. Way, way more common that you would imagine and very treatable.
