Design the horizontal arm to break way in an easily repaired/reset way? Also do a camera flash when it happens.

It ain't gonna work that way. Nearby they built a new bridge over a wide piece of water. It has signs saying not to dive from the bridge but guess what happens when the weather is nice...
The whole problem with curb side charging is that A) it is expensive to install and maintain and B) it will be obsolete within 10 to 20 years either due to batteries getting better and/or hydrogen taking over. It is an utter waste of money either way. And think about introduction of new plugs. Chademo is being phased out rapidly (leaving people with a 'Chademo' BEV with a car that can only be used locally). At home charging is just a crutch to bridge the shortcomings of the current crop of BEVs. It will go away.
Marco:
Even if you could build 5-10 MW chargers to get electricity into car batteries nearly as fast as petrol into a tank, those are going to require batteries all of their own just to handle the huge surge power. Every former petrol station would have to become a grid storage site, just to offset some of the cost.
The charging plugs will probably need a water connection too.

The people of a town usually elect that local government, so if charging becomes an issue, they will change their opinion pretty quickly.
The bigger barriers are going to be heritage areas where the solutions will need to blend in as well as possible (but then cars don't exactly blend in with a 19th century village and that doesn't seem to be a big problem, so who knows.)

Benefactors in balaclavas will steal the copper from the cables.

Elections are rarely single-issue local events.
Most people vote tribally based on whether they like the government do jour.
That could be avoided if referendums are commonplace, but the chances of that happening here are zero after the Brexit fiasco.

As someone who has had to deal with a grade II listed house in a conservation area, that is indeed a major impediment.
Provided you can observe from a distance, it is always entertaining when one branch of the government mandates X and another mandates not-X. Typically each case is adjudicated by the courts - eventually.
