This is a non-story. This is what your insurance is for, they will catch any bill for roadside damage.
Tbh I'm glad that the HA do charge for damage caused, else it would come out of the pocket of every taxpayer who can manage not to drive into static objects on a daily basis.
With regards to foreign roads being better than ours, they are but they also have a vastly reduced amount of vehicles using them so any wear and tear is much less than what our roads see. If we want better roads, we either need to reduce the amount of vehicles by half or pay more for the privilege. Trouble is, the easiest way to do that is with tolls but mention that and people are up in arms about the idea.
