@Garlan Garner I'm not sure why you're being so antagonistic. To put the latter half of this thread in a few words, you're saying "why do people care about an unattended car at a supercharger?" Response: "because it's discourteous and could cause bottlenecks". Retort: "you guys are jerks that should mind your own business. I charge every day at a convenient supercharger, and you want to crucify me." In other words, your car is NOT unattended - you're not in it, but you're actually watching it. And from the sound of it, it's actively charging for a good chunk of that time, with maybe half an hour of being idle (depending on how fast you eat, and how much you chew the cud with Wendy and the cook). I don't think anyone would have a problem with that. I certainly wouldn't.
Now let me interject my own experience. On my first Tesla road trip, I pulled in to the Twin Falls, ID supercharger, to find one other car there - a Model S with Idaho plates. I charged from 15% to 90+%, and left. The Model S was still there. I had only two thoughts - "hmm, I wonder if that's a local. Doesn't bother me if he's parked here all day, cause this place is mostly deserted", and "hmm, he's parked in the only pull-in stall. That's kind of unthoughtful of him. A Model X coming through pulling a trailer would have to unhitch, when if this guy would have used a different stall, he could have saved several minutes by using the pull in stall without unhooking. I wonder if the owner of the Model S has even seen an X; they're still pretty rare in Utah and Idaho, let alone one pulling a trailer. He probably hasn't even considered the possibility". When I returned from the road trip, the same Model S was parked in the same stall. My initial thought was "no way does this guy's travel plans exactly coincide with mine. He must work nearby, cause there's no way it can be more convenient to seek out the supercharger and leave your car all day otherwise". Except when I left this time, it was gone. Much to my surprise, when I got to the next supercharger (Tremonton, UT), the car was there. And gone before I left. Huh. So, I have no idea who this guy was, or why it seemed like he was sitting at the supercharger so long. I hold no malice, but I'm curious about what the situation really was.
As for becoming annoyed with ICE cars sitting at gas station pumps - totally, yes, I do. I don't believe people do it in malice, and yes, there are likely times that it's an emergent situation (a sick guy stuck in the bathroom, for example). But really, you're not supposed to leave the vehicle unattended while fueling, so is it really that much of an inconvenience to someone to pull out of the pump and actually park when going in to the store afterwards? I think what really bothers me is that it is the opposite of myself - I try to be aware of my own situation, and not inconvenience others when possible. For example, it's a common practice to not have diesel at all pumps. If I pull into a station and there are plenty of pumps free, I pay attention and choose one that doesn't have diesel - so that if a diesel truck pulls in, he's not waiting on me. I've even gone so far as one time I pulled in to a full station, and ended up in line for a pump that had diesel. It was my turn, and I had gotten out to swipe my card. At about the same time, a diesel truck pulled up, and a neighboring unleaded only pump freed up. I got back in my car, and switched to the regular pump, which let the diesel guy fill up at the same time. A minor inconvenience to me, but saved the other guy at least five minutes.
A similar example that annoys me to no end is visitors to my home not taking any thought to where they park. I have a two car garage, and three car driveway. My utility trailer usually sits in the third car portion, not blocking access to the garage. Anecdotally, my own family members will routinely park in front of the trailer, so that if someone needs to leave while they are there, they don't need to move. But my wife's family - not only do they usually park directly in front of the garage, they'll often park in the middle of the two car section, meaning neither car can get out of the garage (or if another visitor arrives, they must now park in the street (depending on if the spot in front of the trailer is already occupied)). Even after pointing this out, they try to improve, but sometimes they'll park kind of in front of the trailer, but still blocking part of the garage. Or on the opposite side, they'll park partway on the street, blocking the mailbox and part of the driveway, causing an inconvenience to the mailman. All because they can't be bothered to take a split second when they pull up as to where they should park in order to minimize the probability of future inconvenience to someone else.
I also get annoyed when I see non handicapped people park in handicap stalls. No, it doesn't bother me. And yes, there are likely times when it's an ailment I can't see with my eyes, or they just don't have their handicap permit with them or something. But in general, it's just someone being selfish, that think's that "usually" they're not hurting anyone else, but it still irks me because sometimes it does inconvenience others. If we finally get back to supercharging - in the low probability scenario (depending on the supercharger) of getting ICEd by another Tesla, it's not just a few minute inconvenience. It could be
hours that someone can't charge, potentially affecting travel plans all day. So yeah, if you're hanging out at an empty supercharger for hours, I likely won't get upset at that one instance, but I do take issue with an attitude of "mind your own business, it's not bothering anyone [that I know of]".
