I have a friend who has a Tesla, and I’ve ridden in it several times, and we’ve talked about the new Model 3 as well. I don’t know how much difference there would be between his and the more mid-range model, but I could definitely see it as a daily driver. The way it works for him is he has a special plug in his garage and it has a timer on it to charge up at night when the price of electricity is cheaper, so his cost per mile is even cheaper than it would otherwise be.
For the vast majority of people, the range of 200-300 miles is plenty for most purposes. Even for long trips, he does have access to the quick charge, which can refill the battery in about an hour. And while that’s good, if one is going on a particularly long road trip, like say 1000 miles, I wouldn’t mind stopping for an hour once, but having to stop that long 3 times would be too much. Plus, as far as I know, these quick charging stations aren’t exactly ubiquitous, which means planning a trip means ensuring that one never gets too far away from one. I do know that he’s driven his Tesla from here (DC area) to Miami and back before without issue.
I have also heard that Tesla is looking at expanding that infrastructure, and even looking at doing a faster, though more expensive, method of extending range by just swapping batteries, which means that a Tesla could potentially reset its range in a similar amount of time to a typical combustion engine refueling.
The other issue I see is just with regard to charging in general. I live in an apartment, so I’m not even sure how I could charge an electric car at home. The best case scenario is I could hope for a good spot and run an extension cord and hope no one steals it. I’m actually surprised to see that they offer free charging in the parking garage at my new job, but there’s only one or two stations, and they’re often taken. So I can see this being a problem, even at the lower price point, for a lot of typical families that live in an apartment or condo and don’t have easy access to charging at home or work.
Personally, I don’t see the range as an issue for me, since I don’t take many long road trips, so I’d probably save more than enough from gas that I could rent a car for those occasions and still turn out ahead. It’s the latter problem about the charging infrastructure for typical families that I think will be a barrier. Maybe if these cars get adopted quickly it will encourage some additional investment in the charging infrastructure. However, when I move to a new place, hopefully a townhouse or SFH, I’ll definitely seriously consider purchasing one of these cars.
