Not much sign of 'flooding' where I live [East Yarkshire, up on the Wolds]... Merely the occasional lake-size puddle.
Back when-I-worked [I am a not-work now...One should not be labelled 'retirees' or OAPs' , or even, 'retired' any more. I left the Civil Service as an Uncivil Servant, no desk, no office, shared computer, plenty of outdoors work]...I taught military personnel the initial fundamentals of driving 'off-road'....[amongst other weird driving skills]...Including how to 'deal with large water crossings, etc.
That definitely did not involve huge bow waves, dramatic [for facebook?] splashes, and high speeds [faster than a swimmer's speed is high for water]..
During past flooding events [lower down than where I am living at present] I recall having to use my '87 [600 quid, not 60 000 quid!!]...Volvo 740 to rescue my daughter from the clutches of her grandma in Beverley..access to which was entirely cut off due to flooded roads. Using sensible speeds, sensible gears, sensible positioning, etc I had no difficulties getting to & from...twice, as it happened. Biggest issue was the abandonment of apparently eminently more suitable vehicles all over the place, especially where I wanted to be.
Biggest danger was what lurked underneath the surface of the watter.....As it happened, I forwent the primary advice of conducting a foot recce before driving through. Luckily I didn't come across any displaced manhole covers, etc.
The delight on dearest daughter's face when I picked her up made it all worthwhile.
One thing I took away from any flooding episodes [aside from wet feet] was to avoid buying anything from PSA....Indeed, anything that might have what resembles a computer controlling things.
I am still somewhat reluctant today!
