Fundamentally I don’t care about cars. I want reliable transport available 24/7, ideally for a given price per mile. The costs of a true per-mile option which I can guarentee is available at 3am is not available where I live (taxis don’t fill this niche), so until then it’s Capital (for the car amortised over say 3 years - I buy second hand and don’t worry about deprecation) Time based price (insurance, tax, some maintenence) Mile price (petrol, some maintenence) Location price (top road, parking) This encourages me to use the car more once I have it though, there should be a better way to smooth occasional use (which all travel is - 95% of the time my car sits idle even if I drive an hour a day)
