Balerno does not have the same traffic as roseburn so the analogy is not analogous. However, the Main Street was pedestrianised by blocking the top of the road and rerouting traffic on a slight detour. This was done decades ago. There were rumblings about shops going out of business but this is actually down to the high rent the landlord charges and indeed would be willing to sit with empty shops until he achieves his price. Most people walk to the shops on the Main Street though there are two car parks on either side of the Main Street they are never that busy.
Anyway, yesterday the Fietsclub Balerno stall at the market had a six year old cycling on the street on the electric bike, all ages in between, including an MP (she is getting an electric bike now she says) a 65 year old man who had not been on a bike since he was fifteen (massive smile on his coupon coming down the hill) and a seventy plus chap who walks with the aid of a stick giving it a go (though he has his own electric bike he made himself which he thinks heavier than the one we had, so it must weigh three tonnes). This chap's wife also had a shot, quote from her 'it ate the hill'. We also had prizes donated by EBC for best folding of a Brompton won by lad from Harmeny School, and the EBC smoothie bike which the Aforementioned MP also had a go on, I sang Smooth Operator by Sade at this point. We also had a road bike on rollers. We raised some money for Qhubeka and our stall was still busy at 13.00 hrs when the market was closing.
My point is that controlling where cars go (restricting their access etc) makes for a better community. The shops are not affected by the change to traffic , regardless of what people who wish to whip up hysteria say (shops struggle for their rent but that is down to landlords, out of town shopping, Internet).
Ach, you all know this anyway. But i had twelve bikes in my garage last night (road bike summer, road bike winter, commuter, hack for shopping, bikes of the other residents of the household, a funny wee triang tricycle for a four year old in 1950, a Brompton, a smoothie bike and an electric bike). Could be a record?
