A bad driver is someone who drives unpredictibly. Anytime you are suprised by a move, or questioning what someone's going to do next, you're witnessing a bad driver in action.
Driving predictibly means signalling your intentions in advance (always), changing lanes smoothly and slowly, and staying with the flow of traffic.
After working as a driver for a theatre company for a couple of years, I leaned not to typecast drivers by their vehicles.
I've got more to say but I have to get back to work.
