If you are looking at something to put negligence type pressure on authorities then I think you need to show that design standards were not met >> the systems did not check the standards were met / they knew the standards were not met and didn't do anything about it >> it ended up causing injury/damage.
The best way to start down that route would probably be to write to the roads authority, explaining why you feel that a particular location is dangerous because of the design, and ask that they carry out a safety audit. A few of those received and a failure to follow up/act/find money for an identified defect then might give you ammunition.
A map type reporting system on it's own is easier to right off as being traffic conflicts for other reasons than the design, although obviously if you start to get 100s of reports from one place it should raise concerns.....
