We live on a close. My neighbour regularly lets her 13 year old son drive their cars. Guests do the same. One of the cars is a massive overfinch! I've told her before I think it is very dangerous & if he gets caught he could be prosecuted but she acts like she has no control over it. Surely you can just not give him the keys! It is not always quiet & there are lots of kids around. I want to report it but if she finds out its me it will cause a lot of trouble
