Whilst everyone else is in sharing mood...
My commute is about 16km from Concord into Sydney.
Door to door, the bike takes about 35 min (record just over 30 min).
The train, including the walk at each end, probably about 45-50min if the trains are working, which is a bit of a lottery these days.
I don't have a second car that I can use, so that is ruled out. A collegue that lives in Strathfield (neighbouring suburb) assures me the car takes about 40min on a normal morning peak down P'matta Road.
Some of the roads have marked lanes, some don't, but pretty much all of them are bumper-to-bumper with cars. I don't let the bad drivers bother me too much 'cos there are so many more good drivers that are just trying to get from A to B as fast as they can (I'm faster - ha ha!).
Sometimes you get a blocker - you know the type, they zoom past you, only to stop at the red light 100m up the road. They then try to put the car in the gutter, blocking you from getting through. They can't block both sides though... Most of the time, I'm happy to wait behind the queue at the lights, but I _always_ get in front of a blocker.
I like trucks - they are driven by professionals and they give you something to draft behind (sometimes). I don't care so much for the people that fly up the rat-races - the quiet streets that are better for bikes...
My simple rule: In front of me? = my problem. Behind me? = your problem.
Works well enough...
