Now that I cycle to work pretty much every day, and have the odd chat to other cyclists, they're just as insane as I thought. I only use proper bike lanes and dedicated bike paths to avoid getting in the way of cars. I swear cycling attracts people who just like to be dicks. They ride out in front of oncoming traffic and then take the video recording of the near miss to the police, acting like a hero. And they all have a flawed argument they always fall back on; it's legal to take up the left lane. It's also legal to drive down the left lane doing 30km/h, but you're still a dick.
I have changed my attitude a bit on the bike lanes clogging up the roads though. You can travel quite a distance on a bike very easily. More people should give cycling a go. Then the already created bike lanes will be used more and that frees up the road for cars that need it.
