This afternoon, around 17h00 or so, I am on Corlett Drive, going past Wanderers Cricket Ground, towards Melrose Arch, in the right lane.
In front of me is a woman (with about the same fashion sense as Baleka Mbeti), in a Porsche Panamera (the base-line model), with wipers flailing away on the fast setting on a perfectly dry windscreen - it had rained about 30 minutes previously in that area, but very lightly, and her Porsche was the ONLY vehicle that still had its wipers on.
The road was already dried out from the residual heat of being baked by the sun all day long, so there was no spray at all being thrown up from the tyres of the vehicles in front of her, justifying the wipers being on.
Every time when she stopped momentarily due to high traffic volumes, the flailing wipers slowed down to their lowest 'speed-sensitive' setting, she diverted her attention away from the traffic in front of her, and either fiddled with a cell-phone or tablet, or something else in the centre console area, to such an extent that, when the traffic began moving again, I had to hoot to draw her attention to the fact that she was still standing still, and delaying all the traffic behind her.
Whenever she pulled off to close the chasm, the wipers resumed their frenetic to-and-fro on a dry windscreen again.
Eventually she pulled into a glide off to turn right, and I was now alongside her. I gestured to her to wind down her window, so I could tell her that her wipers were still on, as she seemed totally oblivious to this fact, but she refused to wind down her window.
I then used my arms to mimic the flailing wipers, and this seemed to be a 'eureka' moment for her, as she then pulled and tugged on every stalk protruding from the steering column, until the wipers eventually ceased their 'dance of the dervishes' and returned to their parked position.
It still boggles the mind that people drive these 'technological marvels' with all the bells & whistles, but have no clue as to how to utilise them effectively at all - surely a car of that level would have an AUTO setting that would turn OFF the wipers when it was no longer raining, without the need for 'distracted human intervention' to enable that to take place.
