Simply saying 'just drive' is a very simplistic approach to a very complex problem. If she could 'just derive' she wouldn't be posing on this forum. There is much more to it than that. Depth perception, peripheral vision , looking ahead to anticipate danger, cars overtaking you, trucks blocking your vision, people opening their door on you at shopping centres, parking in narrow positions, going across roundabouts...the just goes on and on. it is more complex than 'just driving.'
