Mine was in my clio while driving in the pitch black of night....
It had been raining lots (as it does in Cornwall), and I was taking my m8 home with my G/F in the car too...
I was driving in a particularly dark and bendy bit of the bypass....
when all of a sudden this huge wall of water was thrown up from the left side of the car and up over the bonnet as I had just hit a huge puddle I did not see in the dark.
scared the hell out of my then G/F, me too...
but that was not the worst bit!
the car speedometer jumped from 40 to 90 MPH!
I was AQUAPLAINING!
The poor clio started to spin!
at this point I was really starting to get scared!
40MPH in a spin!
I ended up in the wrong lane, facing the wrong way....
with a aticulated truck coming towards me!
THAT IS WAY TOO SCARY TO REPEAT!
the truck manged to stop by the way and I managed to restart the clio with the truck drivers help!
