There is a lot of hypocrisy and dare I say confusion re cycle helmets. One thing is sure, more people in cars die from head injuries each year than cyclists so please save a car user by supporting the e-petition at
http://epetitions.direct.gov.uk/petitions/4737
BTW, the trap door to my loft fell on my head last week, maybe we could have and e-petition to protect the heads of people who walk under unsafe trap doors :-)
