that's the same with my misses, I'm always telling her to slow down, leave a bigger gap btw cars, and stop breaking late
it took my misses 5 or 7 times to pass her practical test because of stupid and million to one things happening while taking her test
a farmer in a tractor, a million to one chance in Manchester, he indicated for her to over take him, she left it a bit late and oncoming traffic appeared, another time, stopped at a mini round about, she indicated to a guy at another junction to go, he didn't so she flashed her lights again, he didn't go and so they both went at the same time, another time at temporary traffic lights, there was no sign saying 'wait here' so she stopped too near the lights
