But pricing isn't the only thing that drives people off public transport and onto overcrowded road. There is also convenience and reliability. Regardless of cost of tickets people will vote with their feet and opt to drive if the train is unreliable, with poor service intervals, overcrowded and uncomfortable. And to deal with both ticket costs and reliability there needs to be very major investment, which will likely pay back in terms of economic growth but that will take a long while. In my view it is worth it.
