There is no gas, no oil changes, no brake jobs (regenerative braking provides most of the stopping power), no alternator, no spark plugs, no exhaust system, no belts, etc. 

And then once I’ve got perhaps 500k ‘ish, transitioning to a more conservative/passive investment model which will let me take my foot off the gas and enjoy life on my terms.Right now my favorite option is saving up and being very frugal for a couple years, trying to put back 50k, and then beginning to invest that as an equity investor multiple times per year until I reach a certain point at which I can meaningfully invest in a more passive strategy like notes, or something like that.
