It is quite new (17-16 years old I think!). It will be also expanded in the future, to cover more areas. As it is the only almost fully accessible mean of public transport in Athens, it is a big help for wheelchair users in the town!
In Thesaloniki also there are plans for the construction of a metro line. However, it takes them so long to proceed with them, that this subject has become a king of joke here!

Travel indeed is expensive! Although, I think that there are always ways to keep the costs in a “normal” level 🙂

The only place I found relatively cheap wheelchair taxis is Barcelona. By the way very accessible city (I traveled there many years ago though).
