I got this in my email today
http://maps.sa.gov.au/cycleinstead/
had a play and its suggested route for me is to cross 3-4 busy main roads (not at traffic lights).
I never liked doing this in a car and I find it much worse on a bike. Those little left onto main roads then first right across the other sides are not much better. I prefer to ride on the main road than to take back streets and have to cross main roads. If I didn't have to cross I'd probably take back roads more often than I do.
What are other peoples opinions on cross main roads/turning right on to main roads? Anyone do/like it and have opinions how to navigate it well?
