The cost of the fuel/energy is less than 10%…
So how exactly has the cost of fuel “allowed the end cost of public transport to escalate beyond all reason”? Based on your figures, if they got the fuel for free then the trip would still cost 4 times as much as it does in Germany.
Oh, and of course that’s all without getting into the point that train companies don’t pay £6.30 a gallon!
BTW, are the rolly eyes because you don’t understand the point that increasing the cost of road fuel would actually make PT relatively cheaper compared to driving given the different cost bases? I certainly can’t see anything in what I wrote which deserved them.
