I'm one of those people freken awful at math!
1) I continue my usual work while charging during my lunch breaks, so not much time is wasted there.
2) My local supercharger is next to where I usually spend lunch at anyway, so basically zero extra travel.
3) Can't speak much for maintenance, but I'm used to the usual 30+ min wait times... in addition to the 1+ hour actual charging times.
4) Joke's on them, I'm already dead inside!
5) That'd be nice, as long as they don't take multiple hours.
I've spent almost $1k in roughly half a year in just supercharging costs alone. I cannot charge at home as all quotes for installing a plug for my spot in my apartment's parking have been astronomically high, and I've been house shopping for a while now so I don't see it being worth spending so much on. My employer is also unwilling to install a plug in my parking space.
Assuming I still haven't found a place to charge at home, I would easily end up spending those $5k on supercharging alone in 2 years from now, thus saving me money after that. Earlier if supercharging costs increase again. Kinda makes me wish I had gone for the performance Model 3, rather than my RWD.
Every case has its corner.
You might consider selling your RWD Model 3 and getting a S P85D or something will FUSC. Smokes a 3P even.
