It could be you ! or worse

1030 am 12/03/13.
Leaving M42 onto M40 Southbound. Overtaking 6 wheeler rigid fridge box.
I had to swerve and brake hard due to vehicle cutting into half my lane. no problem, happens lots, probably mobile phone user i thought.
I overtook, and guess what :
He was rubbing off a lotto scratchcard on his steering wheel !!! And was still oblivious to me…
Pulled into Warwick S/B and spoke to transporter who witnessed it, he said he had probably won and was excited lol

Anyone seen worse examples of idiocy ?

All the time.

I just let it go over my head unless it is dangerous to extreme or directly affects me (ie a collision).

Worst I came across was a driver having what looked like a seizure in lane 1 swerving all over place. 999 call and lots of blue lights 8 minutes later.
