Over the weekend, quite a number of news article on illegal car modding, racing, etc...
Today ST forums has a posting whereby the writer proposes to penalise the workshop that does the illegal modifications.
IMHO, it is a good idea since in theory, certain modifications of car is illegal and certainly anyone who offers or faciliates such services is abetting the crime... It is just the same as penalising the shops which sell cigarettes to underage kids...
