I'm sure some don't understand the real costs. But most are doing what they think they need to do in the here and now and, to be honest, if people are really trying to minimize car costs, they're probably at least a bit less than IRS allowances.
In some sense that's a tautology. Everything that anybody is doing is because they've made the decision that that is the best thing for them at that time given their current circumstances. Outside of that I wouldn't label it this way. Driving Uber is not the only option in America.
Because remember that most jobs require you to show up daily at your own expense during off-the-clock time causing vehicle depreciation all the same.
And that is a difficult reality.
It doesn't cost that. That number is what the IRS accepts for deducting mileage expenses. That doesn't mean that's what it costs everyone. An older model and fuel efficient car will be less than half that on a per mile basis.
They just don’t have an option for better pay:quality of life at work ratio. Which generally applies to the work of 95% of the people in the world, they simply don’t have a better option.
