Our friend Basingwerk is oft heard referring to the evils of Testosterone Man, and I'm sure we can all conjour up a mental image of the type of driver/driving to which he is referring. The thing is, I'm not altogether concerned about TM and his appalling attitude towards driving. You see I can spot him coming from a mile away and can take preventive measures which ensure we don't come into contact. Sure, I deplore his tailgating and lane chopping, but don't wish to be involved in his next accident.
No, I'm more concerned about Mindless Maureen and Daydreaming Dave because
I have to think for
them. Maureen and Dave concentrate only on what is happening in their immediate vicinity. I don't get alongside them through roundabouts because they have a nasty habit of drifting across lanes, I have to create their 'stupidity space' for them.
I saw Maureen today in fact, overtaking me on the M54 in her little red Peugot yet oddly drifting towards my rear offside; in my mirrrors a collision looked possible. A toot of the horn and a jink to the left onto the hard-shoulder soon woke her up, or rather forced her to lower her outstretched left arm which was holding a mobile phone into whose hypnotic screen she was staring. Oh, did you know, Maureen is a nurse

You think she'd know better
Dave is just as bad. He seldom looks at anything that is more than 3 foot ahead of him, comes flying into the close where he lives giving nary a thought to the kids playing nearby. His wife (another Maureen oddly) does exactly the same thing.
The difference between TM and Maureen/Dave is that TM probably knows what he's doing, although he pisses a lot of people off doing it. There's also a chance that TM will sooner or later attract the attention of the police, something Maureen and Dave are unlikely to do as they blend in with their clones. And with modern road safety policy being the mess it is, we're creatng more and more Maureens and Daves all the time.
