OK, there's only two instalments though, I don't make a habit of getting done for speeding in every country I visit
Anyway, we move to Uruguay. I was working and living in Chile at the time, and had just gone to Uruguay for a couple of days to look at a site up in the north near the Brazil border. I would point out that Chile, Argentina and Uruguay are all quite 'European' in many ways (we won't go into the colonial history at this point), overt corruption is rare, in fact Uruguay is the Switzerland of South America in that a lot of the banking and financial services are centred there. But we digress ...
It was a beautiful, bright Sunday morning and I was driving back to Montevideo. Good quality road, virtually dead straight, no other traffic, I was cruising at about 70-75 although the limit was 65. I came over a small crest and saw a couple of figures standing next to motorbikes about quarter of a mile away. Realised too late they had a speed gun and were waving me over. Bu$$er.
So we had a brief chat, they thought I was German for some reason, but anyway they confiscated my licence and said I would have to go to the traffic police station in the next town and pay a fine to get it back. Frankly I didn't care about the licence (it was just one of those £3 international ones you used to buy from the AA, can you still do that?) but didn't want to openly say that so I went along with it. I had very little cash on me, maybe $80, and needed some for tolls on the road further south, so when I got to the police station I put most of it in the glove box and went in with about $30.
Because it was Sunday there was only one policeman on duty in the station, he was obviously bored, so I explained what had happened, what I was doing etc, all very relaxed. Meanwhile the two motorbike cops turned up with my licence. Time to get to the nitty-gritty. "You have to pay a fine". "How much?" "$80". "I don't have that on much on me, I'm only here for the weekend and I'm using credit cards for hotel, car hire, fuel etc". "You could go to a bank in the town". "It's Sunday" (this was before ATMs were common, and besides I didn't want to go down that route). Endgame approaching, you could see it coming for miles ...
"So how much have you got?". Bong! "About $30". A short silence, then the killer question "Do you need a receipt?"

"Er, no not really, does it make a difference?" (it would just go down as unreceipted expenses as far as I was concerned). "Well, if you need a receipt the fine is $80, if you don't it's $30". Bong, what a coincidence, that's exactly what I have! "OK, I don't need a receipt, here's the $30". "Thanks, here's your licence".
So we all said our goodbyes and I started to walk out. As I got to the door the desk sergeant called over to me "Do you know Florida?". "Only that it's a town between here and Montevideo". "Well, the police there have also just had a batch of new speed guns delivered - mind how you go!" I could hardly drive off for 5 minutes for laughing ...
