Hope you reported it to the police. If he does it again keep your doors locked and your hand on the car horn to raise attention. Drive to a well-lit area like garage and continue doing the same.
Witnessed driving like what can only be described as a complete moron with a disregard for anybody who happens to be on the road at the same time.
There truly is no end to this female driver's talents - tailgating, exceeding the speed limit, applying makeup whilst driving and if that weren't enough - she drives a BMW and of course, made the obligatory manoeuvre without any use of indicators.
If you happen to see this person on the road, pull over and wait for her to go away.
Not sure if anon2016 spotted her in the same area (Warrington).
Very dangerous BMW driver
