That part he understands - that Tesla charging stations are popular.
I think the whole recharging thing with EV's, (not just Tesla's), has to be experienced and realized
over time, in order to be actually understood..... And / or successfully dealt with.
For example, people expect to wait at the doctors office. There is no way around it. But nobody likes it, or ever seems to get used to it. Especially if it drags on well past your appointment time. People have other things to do in life, and a limited amount of time to get them done.
Most of the time with health care and dental appointments, the wait is longer than expected. And it certainly doesn't improve anyone's mood when you are forced to do it.
But again, there is no way around it. (I've switched doctors more than once due to unnecessarily long wait times. For both getting in to see them, as well as being forced to wait well past my appointment time when I do).
With EV's it's different. So yeah, you buy the car in good faith, full well expecting to have to wait in order to recharge it...... At least if you plan to go anywhere in the thing, besides running local errands.
But the idea of having to sit around for at least 45 minutes to an hour,
after you wait to plug it in, all the while seeing people pull into the gas station across the street, and fill up and leave in 5 minutes, isn't going to sit well with him. In fact I'm willing to bet that he'll find it downright aggravating the first time he actually has to do it.
Especially if it's raining, freezing cold, or if there is
ANY kind of inclimate weather involved. And you have to remember, not all these things are directly across the street from somewhere you can go and waste 45 minutes to an hour while your battery recharges.
And I can all but guarantee you, it will irritate someone with limited patience like your dad, even more. I would try to find somewhere that rents these things, and get him to try one for a month or 2. And do some serious driving with it. Before taking the financial plunge and sinking hard earned money into one.
Right now EV's are simply too restrictive to directly compete with the ICE vehicles he has become used to driving his entire life...... And take 5 minutes to fill up.
