I had to laugh at this report.
A busy road in North Yorkshire was turned into an “ice rink” after a lorry overturned – spilling its entire load of instant mashed potato.
The heavy-goods vehicle crashed at around 3.30pm on Saturday on a section of the A64, North Yorkshire, causing perilous driving conditions as the mashed potato began to swell.
The road was shut down in both directions at the Castle Junction for six hours.
. . .
A police spokesman said: "Instant mash is covering the road and cars have skidded as a result of the mash swelling up."
There's more at the link.
If several vehicles collide after skidding on a road full of mashed potato, would that be a new version of 'bangers and mash'? (For those who don't know the English term, see here.)
