Provision differs by local authority, but there are some areas of London where they appear to have put a plug on almost every streetlight.

I’m assuming that there are still far more cars than there are streetlights. It might work, but god does it sound stressful never knowing if you’ll get lucky and find a streetlight parking spot.

They cluster them in at least 3's. If the three by my house are completely blocked (the cable is almost as long as the car), in use, or broken (one was kicked in recently, now fixed) and I desperately need a charge (which has only happened once) there are at 10-15 more within 5 or so minutes walk.

Ubitricity has shown a concept where they have smaller extender posts off the lamp posts, which I guess they'll be able to install if an area gets really busy.

Absolutely. I think there are more on-street charging stations in that neighbourhood than there are in my entire city...

Are they typical 15 or 20 amp circuits? (whatever the typical circuit is in the UK)

15 amps at 230v won't charge very quickly.

It's 20amp & says it's 5kW (but might be 4.8?). More than enough to charge a car overnight.
