Best cycling sight of the holiday so far: it’s perfectly safe and acceptable for sensible ten-year-olds to cycle around on their own on paths and roads.
Good quality cycle infrastructure is well integrated into the road network. Even on a busy street, the cycle lane is miraculously free of parked cars and wandering pedestrians.
Most depressing thought of the holiday so far: for a number of years we have cycled the last British bit between Manningtree station and Harwich. The final few miles is part of the National Cycle Network and it’s on a fairly busy road. Not dreadful, but not great either . . . and in all those years, while car traffic has increased, the cycle route has never been improved. And it probably never will be now.
