Bike Sidehack

Image swiped from Speedgoat

Saw one of these for the first time this weekend. A bicycle sidecar from Chariot. Besides being more complicated to connect, and making bike parking a hassle, I suppose the main effect is that you can look at your kid. If that's important, time to get a bakfiets. Has anyone out there ever used one? Does it allow you to take left turns like this?
