I have found that Seroquel and some strong anxiolytics when I had just come out of hospital made it harder to stay focused and aware of distances and slowed down my reaction times, so I didn't drive when on those. But most of my meds don't affect me badly and I drive without a problem. I avoid driving in heavy traffic because I find it stressful and not sustainable if I'm to avoid another episode of psychosis. That isn't because I'm not capable - it's just a personal preference to manage my anxiety and stress.
