@Panama Jack, I get your cynical remark.
But I'm genuinely glad that they do not just accept and convert any banana-licence in the UAE. Driving standards are already poor enough here as it is, so any unverifiable and unknown licence-owners will just have to, at least, go for a driving test. I believe that's fair enough, and would welcome even stricter rules (and better training standards).
Anybody who has ever been hit by a truck or a taxi driver with a stupid grin on his face saying "oooh, sorrysorrysorry my friend" would probably agree.
