In places where the pavement is too narrow to incorporate a cycleway, it is often marked out on the road, even across junctions.
And of course, cyclists use bus lanes.
Most importantly, cars are used to bikes, and bikes are used to pedestrians. They look out for each other; there seems to be less aggression.
There is definitely less helmet-wearing, and hardly any day-glo clothing worn by cyclists. Lots of small children are on their own bikes, with the very small ones sometimes being towed in trailers.
