Aggressive driver

Witnessed a driver of Kaylin Tours yesterday (white Avanza CA429-890), driving like a complete nutcase yesterday, swerving in an out of lanes and even flicking off a driver. Reckless driving and appalling behaviour. Not sure if she was in a rush to get to a client, or to get home (it was late in the afternoon), but would never use or suggest this company to anyone based on her actions.
