You should, in general, get at the right hand side of the lane going straight - tho' sometimes I'm just over that line, especially if there isn't anybody in the right hand turn lane, 'cause the right turners will usually be all the way over to the right of their lane.

YOu don't want to be to the right of people turning right when you're going straight - especially if there's a right turn on red, 'cause then you're keeping the cars from turning right.

THe most common cause of bike-car accidents is the "Right hook" - when a car turns right in front of you - and it is a lot more likely to happen if you're too far to the right.

In my experience (a *not* too busy town), drivers are **much** happier when I ride like a car. I get treated like a tractor or something... but given room. (Not so good when I'm going down the busier streets at rush hour...)
