"Oh Shit" moments...

^As a driver as well, I'd happily accept the call for regular testing / refresher courses for drivers. Truth be told I wasn't really taught to drive, simply taught to pass the test. From that point drivers go off on some radically differing tangents - those who generally seek to improve their skills and drive well and the more selfish, self involved types who are the bane of other road users lives. Take those 'skills' back to a review test drive and see an improvement I say.
