As an "ex-Brit" (never been a nationalist or patriot of any type) living in Spain, there seems to be some paranoia in the UK about bikes (and everything else) and Brussels. From here, no-one in government or EU parliament are anti-bikes, they are pro-safety, extreme E4 rules apply to cars too!
Sorry, bikes are regarded as essential transport in most of the EU.
There is no way that any legislative assembly with borders on the med could get away with anti-bike laws, so many people use bikes and scooters a primary transport.
Spain is very bike friendly, Italy, Greeece and even S. France have no problems whatsoever with motorcycles, they are essential to ordinary working folks, like UK in the 50's.
Also: what government these days goes against the needs of
Big Business?
Do even the most paranoid MAG members think that the EU will legislate against Honda, Kawasaki Heavy Industries, BMW, the big Italian conglomerates that control Ducati, Cagiva, MV .......(and China, Tata Industries of India)

Higher than that level,
the world is owned by a couple of dozen billionaires who have major oil/transportation/manufacturing investments. They will not accept little governments restricting their profit potential.
The problem is the UK mindset, the Brits love rules and police them to the limit. Everywhere else in Europe, the rules are just guidelines.
The bikes I ride here are far more illegal than I rode in the UK (try parking at Devil's Bridge, Matlock, Bala , Cat&Fiddle with a dodgy bike, try to avoid the average-speed cameras, the helicopter patrols...! How many tickets can you collect in a day?), the difference is that the cops here don't give a f**k unless you are doing something stupid.
Do lobbying and pressure groups do any good or is it just a waste of money pretending that democracy really works ?
Please comment.

ps, In 2001 I witnessed a sad cop measuring numbers on a bike reg plate with a vernier caliper on a car park at Matlock, he was upset about the abuse that our little club directed at him.
