This dated well – three of my top picks were roundabouts, and just recently I got wiped out at a tiny residential roundabout in Rolleston, by a car not giving way.

Root cause was that classic set of

* Car not stopping completely (why, its a give way not a stop)
* Fat A-pillar on that model of car (airbags are more important than visibility?)
* and my motion through the intersection kept me in the driver’s blind spot the whole way.

A 6-foot flagpole, blinking daytime running lights, high vis clothing, and an unusual bike were all nothing because I was occulted by the car’s structure and unfortunate timing.

So, as an update, I would say that all roundabouts are purely for cars and not for bikes.

I can not think of any good cycling infrastructure that involves a roundabout.

* Sockburn Roundabout – I ride the footpath here.
* Ferry Road roundabout – take the lane
* Cranmer and Latimer Square “wiggles” at each end. – take the lane, keep an eye open behind
* Halswell Junction/Springs Road roundabout – even using the bike “paths” you have to be alert

Thing is, I tend to think of roads that are not-good, more than intersections.

* Hornby shops
* Riccarton Road shopping area
* Pound road
* Old Waimak bridge

And some are worst at night.

* Waterloo Road (dark)
* Jones Road (dark)
