What do you dislike out of interest?
I dislike the enforced VAT legislation which prevents the government from adjusting VAT to a level that suits the economy, I dislike the freedom of movement since the extension of the EU to include a range of disparate economies, I dislike the unfit for purpose NEDC vehicle testing system for emissions and fuel economy, etc. There is probably more, but then there are various things I really like, too - such as freedom of movement between similar economies, consumer protection legislation, etc.
