To be fair, costings like this don't take into account wear and tear, decreasing value etc.
As we are now 19 years away from net zero emissions, I would happily see anti car measures across all counties not just in Newcastle city centre. People have had the easy, responsibility-free life for too long. Public transport is the only viable option, people can either use it, and accept a degree of responsibility , or carry on the way they are and find themselves in deep water come 2040.
They're costs that come out of my bank account on the day rather than taking into account the overall costs of running a car - which in fairness still apply regardless of which mode of transport I pick for that rare daytime journey into Newcastle, rather than my usual car journeys that'll take 30 minutes in the car but 3 hours on a bus etc.
Electric cars will become the norm, and e-scooters may be legalised for private use - both would change my habits. But if buses remain the same, then it'll still be the least favourable option.
