Mr. Money Mustache is famously a staunch critic of car usage, referring to them as "luxury go-karts". Given the shoestring budget requirements of this sub, car insurance and maintenance would eat up too much of my annual spend in my opinion. So, what am I to do? Today I live in a somewhat walkable suburb, and have been thinking about this question for a while, but I am still skeptical about my plan's viability. Here it is:

1. For relatively short commutes, ie <10 miles, I plan on using an e-bike
2. For longer intracity commutes... public transport? Uber? <--This one is still a work in progress, and I am still unsatisfied with my options.
3. For intrastate transport I think I'll have to rely on Greyhound buses or some equivalent.
4. For interstate transport low-cost airlines like spirit and frontier seem to be a good option.

Has anyone else thought about this? What are your plans?

Edit: Added points to distinguish between inter and intra-state long distance travel(points 3 and 4)
