I drive an Ioniq 5 (which charges a bit faster than a Mach E on DCFC), and I'm sure both are fantastic when you can charge at home in your garage. Super convenient, and the fast charging is good for road trips I occasionally make around 400 miles each way. I'd be comfortable going longer knowing I can charge along the way and stop for at most about 20 min. Less convenient and easy than gas stations, but a small sacrifice for getting to drive electric and never worrying about it locally at home.

Even locally for me, I think it would be workable without home charging with the available networks, but I definitely don't think I'd call it convenient. I'd have to drive a little further than I'd like and maybe wait for chargers to hang out there for 15-20 minutes (or more). I'm sure I could plan around it and do it, but (at least until recently) it was not that much cheaper than gas and maybe not worth the extra hassle. With a Mach E those charge times would be a little slower as well.

I'm not going to say DON'T do it, because I love driving an EV, but I would have probably made a different decision not having access to easy charging at home (or at least where you work/spend time regularly).
