I've had some very unlucky accidents. But. granted I have also been very reckless at times. Nowadays I drive pretty slow, occasionally going 10mph above speed limit on highway.
I've totalled 3 cars in my 12 years of driving. And had a few fenders in the driveway when I was younger. And one really frightening crash when I was 16 where I am lucky to be alive.

Anyways, I wouldn't attribute my recklessness to being bipolar. However, some instances yes, I might of been manic.

Honestly, we shouldn't be driving if we're manic or psychotic its just not safe.
