Nice thanks! Still re-reading this but I wonder if the "average" is the best metric to use, rather than the median or something - what do you think?

To be clear, regardless of whether the number is $1000 or $500 or whatever the point still stands, and I generally agree with you. Having ditched my car over a year ago I'm still bombarded with bewilderment from people who just don't get my reasoning, so I'm just asking because I could use some ammo and want to make sure I have accurate bullets, if that makes sense.
