I’ve also completed the questionnaire. My main irritation at the moment is bike lanes that segregate cyclists from traffic but put us with pedestrians. Often, they have high kerbs on the road side (to keep the cars out) but as I ride a fixed, I’m always nervous that my pedal could strike the kerb and cause an accident - happened to me once and I only just managed to stop and remain upright.
Personally, I hate what Kingston have just done in widening the pavements significantly on Kingston Hill and turning half of the pavement into a cycle lane. The problem is that there are regular bus stops (with rubbish bins and concrete posts right in the middle of what is now the cycle bit of the path): this forces cyclists to move left (because the kerb doesn’t let them move right!), into whoever is waiting for the bus. That tends to be mums with pushchairs and elderly people who are likely to be nervous about cyclists, especially on a downhill bit when they could be approaching at speed. Also, the segregation from traffic is so severe that it isn’t that easy for cyclists to move into the cycle lane if they happen to be in the road to start with ( v high kerbs with few spaces and regular bollards just high enough to catch the bottom of many drop bars) - so far I’ve seen two cyclists come a cropper and fall off when trying to enter the cycle lane.
Similarly, I was cycling down the Embankment in central London on Tuesday, which has changed Since I last used it. So little traffic that it’s hard to get an accurate impression. The road was always wide and traffic could travel quickly, but there was a wide bus lane that cyclists could use (and at peak commuting time, there are a LOT of cyclists). Now, they‘ve turned long stretches of the bus lane into a dedicated cycle lane that can’t be used by buses (separated by regular bollards rather than a kerb, fortunately). But the bus stops are still on the inside (obviously), so the buses have to move left across the cycle lane to allow passengers on and odd, and then move back again, into a narrow lane of cars etc. I was there mid-morning so I couldn’t see how it would work in peak traffic, but does seem and odd layout.
