It's a joke that this kind of expense is expected as normal for road infrastructure but when you propose spending the same on rail or public transit it's always "but so expensive!" "What a waste of money!" "Who's paying for it?"

So what if a transit project is over budget? People will use it, and it's possible for these projects to have more ways of measuring value than fare takings - nobody questions the fact that driving your private car on the motorway is free!
