Was just thinking the same as WC, then saw WC had made it anyway. But to reiterate:
I hope that the Council is getting a clear message that a segregated two-way cyclelane along George Street is widely seen as A GOOD THING. The is a key point here. Positive reinforcement of behaviour.
Yes, it would be nice to have the same on Princes St, but we don't want any baby/bathwater disposal incidents. There is a risk that the focus shifts to complaints about Princes St and that quickly creates the impression that "cyclists don't like these plans" and we're back to square one.
Criticism needs to be carefully framed so an already wounded Council isn't given enough of pelting to say we offered you this, but you didn't like it, and it's withdrawn. The risk of one of the most popular and visible media of debate (I'm looking at you, Twitter) is that there is barely room for nuance and, even if there is nuance in the first tweet, it can quickly become "@CECCouncillors I want cyclelanes on Princes Street. I don't like your plans".
So, by all means say it would be even better to have a two-way segregated lane on Princes St, and that it would not take up too much space located between the tramlines and the pavement cafes (and, hey, no one's going to want to sit sipping their latte with a multi-ton tram rumbling by just inches away, so there's space right there), and it wouldn't cost much to do, but let's make sure that at the same time it's clear to them that we think that the suggestions for George St are a real step forward.
