a system like Luas where the majority get €45 as opposed to €100 fine which is usually at the discretion of the officers issuing the fine. From experience of seeing people on the Luas, more often than not people accept it and there is no attitude issues for the most part where as €100 causes problems.
We get complaints about LUAS as well.
Speaking of which -and anecdotal evidence is the worst kind - there are a lot of complaints on twitter in the last month of fainting on the green line in the morning peak. Cant remember seeing that many before.
