I've often driven in 'Continental Europe' and have not yet encountered any of these difficulties - perhaps I'm just lucky - but it's all about awareness and preparation. In any country you can be 'blessed' with a stroppy copper who will bang you up in jail rather than listen to reason. But the laws of other European countries aren't so very different to our own here in the UK or in Eire.
I've travelled pretty extensively throughout Western Europe, having done several 'Road trips' on top of the 'usual' one off trips
1991 - Fiat Twin Cam Register 'holiday' to Italy, taking in France and Italy
1995 - Holiday to Tuscany, via France, Luxembourg, Germany, Austria, car hating Switzerland and Italy
2004 - Collecting my 131 Abarth, home via Italy, Austria, Germany, Luxembourg and France
2005 - Collecting my 131 Racing, home via Italy and France
2006 - Trip to Barcelona, Spain, to ship my sister and her belongings back home
and have seen plenty of UK drivers pulled up at the roadside by the local Bobby for speeding through the countryside, but you get that here!
When I drove to Spain I set my cruise control in Calais and drove until I needed petrol or the loo. I travelled an
average of 67mph to cover the 1,000 miles, and the only time I saw a copper was at a couple of toll points and in Barcelona city, when they were nicking the local Boy Racers for having blue neon lights!
The fact is that yes, you can be nicked for speeding or for driving without lights in a tunnel, and yes you can be fined 150 euros 'on the spot' or have you car impounded - but it doesn't happen every day, and most coppers are sensible.
The trick is to make sure that all of your paperwork is in order and about your person, your car has a GB plate on the back, you have a full set of bulbs and a warning triangle - and that you drive sensibly!
Reading up on signs doesn't take long - most of them are the same throughout Europe, so if you don't know them you deserve to be fined.
Programmes like that drive me mad - they only highlight the worst cases and aren't representative of the 'real World'! I also think that the ferry companies and European Tourism Offices won't be too pleased either, especially as Motoring Tourist numbers are likely to fall sharply anyway as a result of rising fuel prices
