Difficult to argue with someone - one of many - who thinks that the only cost of travelling by car is the fuel.
From https://www.railforums.co.uk/threads/what-the-split-ticketing-sites-don’t-tell-you-the-seat-may-not-be-the-same-for-the-journey.220737/#post-5252641
I've explained many times that that (or close to it, taking into account a tiny sum for tyre/brake wear/servicing*) is a perfectly valid model and the one used by most people, either formally or informally. Modelling as a per-mile rate for the full cost of the car is not the only valid model. Much, much more common is modelling the fixed costs as a monthly/annual cost of "membership" in the "club" of car ownership and journeys at marginal cost.
Once the railway gets this into its thick skull and offers comparable models, such as a National Railcard, they might get more people out of cars.
* Most modern cars have service intervals of 20,000 miles/1 year, which means it's a fixed annual cost for the vast majority of drivers. Regarding tyres, I tend to keep cars for 3-5 years and in that time I'll usually get one full set of new tyres, and so adding a marginal extra journey doesn't affect spend. Brake linings are very cheap, particularly if you can DIY them. Clutches don't generally need replacing these days unless you drive badly, e.g. excess slipping or riding the clutch.
