Generally, driving is 2nd nature for me. Both my college and job have required lots of extra driving over the past few years and I generally have very little to no anxiety whatsoever with it. Once in awhile the DP kicks in while I'm driving, but it has never caused any problems. The worst I had it was driving while bomb stoned in a massive trip, however I still - shockingly, had no problems actually occur outside of the panic of the sensation alone. My body was in auto-pilot as I knew the directions very very well. My dp began way before I ever tried green - and the few times I have tried it only led to either no real noticeable effects and 2 massive trips of paranoia through the roof. Driving naturally can induce a sense of DP in people without DP after very long periods of constant driving on a long stretch of road. Road fatigue for one does sometimes include symptoms of a more natural sense of DP for people that goes away when they finally take a break (sometimes even requiring rest.) So I'm sure some people who have a DP/DR disorder may experience these sensations more often when driving is involved.
