My father is quoted in a recent Vancouver Sun article about bike lanes: Council considers more bike lanes downtown.
He points out how bike lanes make cyclists feel safer, encouraging the use of bikes in urban areas. He also highlights the two greatest dangers to cyclists: people opening car doors in front of them, and drivers making right hand turns into them. Both have come up here before.
In addition to physical protective measures, I think both educational and legal strategies should be pursued. Both of these types of collisions are caused by people not checking their blind spots for incoming cyclists. Driver training should put more emphasis on the importance of this. In addition, I would advocate making it the legal responsibility of someone making a turn or opening a door to check for cyclists. If they fail to do so and cause a collision, they should have to pay compensation to the cyclist and have a penalty applied to their driving license. In egregious cases, perhaps criminal charges should be pursued.
In any event, I very much hope Vancouver continues to make itself a more appealing city for cyclists, and that other cities follow the lead from places like Vancouver, Portland, or the Netherlands.
