So, there I was in Portsmouth, following a Mitsubishi FTO. It was being driven really, really badly. All over the road and going for the "slowest acceleration ever" award at each traffic light. In a 50 limit the car barely got up to 30 and that seemed to take forever.
The back window had what looked like a 90% tint so very difficult to see what the driver was like. I couldn't get past because where the road had two lanes they were either dedicated turn right or there was solid traffic, usually both.
I got around to thinking either drunk (at lunchtime) or on the phone. The weaving between lanes was fairly poor. Where I had to turn right to leave Pompey the car kept left so I thought I was OK. No, at the last moment the driver slammed on the anchors and swerved across the front of my car at the same time and turned right down the same road.
When I got to the roundabout under the M27 where I'd be heading right, I got my chance and passed the car. Sneaked a peek at the driver.
Woman, bleach blonde. Thick glasses. Pink jacket.
Drunk? Didn't seem so. Phone? No.
So what was causing the erratic driving and no use of indicators?
She was 100% engrossed in sucking her thumb. Completely away with it like a baby in a pram. Thumb rammed into gob, fingers curled around her nose. Oblivious to the work around her.
