> although less than it seems once you take into account depreciation of your personal automobile (which is why the future transit and bike options are particularly intriguing.)
Vehicles depreciate a fair bit when they roll straight out of the parking lot.
Vehicles depreciate over time staying parked in your drive way/garage.
Racking up miles on the odometer will definitely inflict wear and tear, especially in wintery climates (read: salt water corrosion), but depreciation will occur regardless.
Where do most personal vehicles end up? Does everybody resell to dealerships or friends/ family/ co-workers/ random people on Craigslist?
Most people have accepted that the resale value a vehicle will be significantly lower than the purchase price, and honestly I think depreciation should be the least of our concerns.
And with regards for sick leave, family leave, and retirement savings that are decoupled from the employer -- look outside of the US and you will find it.
