When you say "people have to take more responsibility for themselves" is that for pedestrians AND motorists? Do road engineers have any responsibility to makes roads safer (take responsibility)? You wanted another lane on Coburg. Does adding more lanes put pedestrians in more danger? Do you  know there is a shrine near The Commons for two killed in a car crash from going too fast? How about the recent crashes into the cinder block walls? Should the speed limit be reduced? Will enforcement work if it only last a few weeks? Can we afford to add more police to "watch" for people speeding? 
Once a person gets a license many believe they are now traffic experts. Do we trust highway engineers  who have four year degrees and 20 years experience (there ARE bad apples)?
Inquiring minds want to know the answers to these questions.
