Easily. The network is already massive and that's almost three years away. Most of the existing network was built in the last 3 years, and they have far more resources now than when they started, so you can count on the pace accelerating. Elon has said from day 1 that the supercharger network would be designed to grow ahead of demand. This is definitely well-planned for and not at all something they're sitting they're frantically wondering how they'll manage. According to their website, there are currently over 3500 superchargers. If they sell 500,000 cars in 2017, which of course they won't nor do they plan to, that's 142 drivers per charger if they didn't build any more. Imagine if you only had to share a gas station with 142 other people total. Do you think you'd ever even see them at all, let alone have to wait? Note that the geographic distribution of chargers matches the distribution of owners, i.e. more chargers in urban areas, so there will not be overload on some and underdemand on others.

If it took me an hour to fill the tank - absolutely. It takes me less than 5 minutes and I often still have to wait in line if I'm forced to fill up on the way to, or way home from work.

  But they know this, and will keep ahead of that demand. Thanksgiving 2018 is a long time away, and building more superchargers is the least of their engineering problems. Very easy to do. And I think you're not grasping how small a number 142 is for a full-fledged gas station. There are over 200 million people in the US with driver's licenses, and over 114,000 gas stations. If only half of those people are driving, that's almost 900 drivers per gas station. 142 is nothing! Particularly since this isn't accounting for the fact that many/most Tesla owners fill up at home. The competition for charging space you're anticipating is simply an imagined worry.
  - mattzito 11y ago
    Sure, but you get that the whole distribution model is different, right? Gas stations accept everyone who has a gas-powered vehicle, and take 5-10 minutes to fill up. Supercharger stations accept people who are on long trips and take 40-something minutes to fill up at best case. So it's reasonable to say that the usage patterns are totally different.
- mikeash 11y ago
  But you never hit the Supercharger on your way to and from work, because you charge at home. You only need Superchargers on long trips. Most people will visit them only a few times a year, so the demand is much lower.
  - mattzito 11y ago
    Right, BUT - everyone tends to make those long trips at the same time. Thanksgiving, Mother's Day, Spring Break, Easter, Passover.
    - mikeash 11y ago
      Most of those trips aren't that long. The average Thanksgiving trip is a bit over 200 miles, for example: http://www.rita.dot.gov/bts/sites/rita.dot.gov.bts/files/publications/america_on_the_go/us_holiday_travel/html/entire.html http://www.rita.dot.gov/bts/sites/rita.dot.gov.bts/files/pub... Maybe 40% of gas cars will need to stop for fuel during a trip of that length, assuming a range of 500 miles and refueling when near empty. EVs should be able to make it directly, since they'll start at 100%. You're absolutely right that the network needs to be sized for peak demand much higher than average demand, but even then I think it's less than what you'd need for the same number of gas cars.
      - ams6110 11y ago
        Why do you assume you're starting at 100%? That doesn't seem like a given to me. You go to work on Wednesday, maybe run a couple of errands, and then leave on your Thanksgiving drive. It's nightime in November so you need the heat and the headlights. There are no superchargers within 50 miles of your planned route. Now what?
        mikeash 11y ago
        Yes, in that scenario you'd have to stop. But then gas station usage goes up too. There's some crossover point where the EVs need more, but I don't think this gets you there. By the way, don't mention headlights. Their power consumption is absolutely negligible. Heat, for sure, but not lights.

> This is definitely well-planned No, it isn't. First, Hawthorne has been a huge pain for owners. Lines waiting to charge. Second, there are several places which are mind-boggling as to why they "planned" it the way they did viz.: Philly to Pittsburgh you have to route through Baltimore and stop at Hagerstown in winter, then stop again at Somerset due to the massive elevation change. If Tesla had put a supercharger at Breezewood there'd be no problem. See the Tesla forum for complaints. > that's 142 drivers per charger This is a straw man. Few people will be charging at the Mitchell, SD supercharger. I chose Newark as an example because it is at a rest stop (contrast with others your have to go out of the way to get to) and it is right in the middle of a large metros. If you want to do the math on how many people will be stopping to charge there spending 30+ minutes each -- again, assuming you get the transformer to yourself -- I don't think it'll work out well.

  Re: Hawthorne, I acknowledge it's not perfect and there will be kinks. And they'll get fixed. Just as the iPhone had imperfections, and they got worked out. Remember hearing people complain how you couldn't run multiple apps at once, a few years ago? Then that faded away, and sales were never slowed. I'm sure you're right, some areas will end up overburdened-- and they'll fix it.
- rdtsc 11y ago
  I like Tesla because it is cool but I would never bother to alter my route or wait in line or do any of those things. Even if I only traveled 2-3 times a years. The reason is, if I buy a luxury/fun/toy car, it has to be a luxury/fun/toy, it cannot be a hassle. Waiting in lines and altering the route to charge is a hassle. I am glad others don't mind but even if I could afford it, until there is a better charging network or some kind of swappable battery thing or something else, I'll stick with hybrids or plain gasoline cars.
  - greglindahl 11y ago
    Yeah, you're definitely not in the Tesla demographic. When Consumer Reports dropped Tesla from the recommended list due to the number of repairs needed, they noted that an astonishing 97% of Tesla owners would buy another one... despite all the hassles. That says a lot about people who buy Teslas.

It takes me 5 minutes to put gas in my car. It takes 40 minutes to quick charge a Tesla (longer for other EVs) Also when analyzing scarcity of chargers you should look at popular travel routes, not population distribution. I'm not saying you're wrong, but your analysis is weak in those points. Disclaimer: I work for a competing car company, any opinions are solely my own.
- GreenPlastic 11y ago
  Am I the only one who dreads going to the gas station and runs the car down to the absolute empty point before getting gas? I really don't ever want to go to a gas station again and would rarely use the supercharger network.
  - csours 11y ago
    There is a range of options nowadays. I think that the portion of liquid fuel only options will decrease over time, and the mix of PHEVs will increase sharply in the very near future. I think electric only makes a lot of sense for many applications, but certainly not all. Anyway, my points above were related to Supercharger congestion in holiday seasons - something that will be even crazier in the Chinese market with the Lunar New Year. I bring up China because they are the largest car market, and the Chinese govt is pushing for fuel efficiency and pollution reduction, both of which electric cars achieve.
  - ams6110 11y ago
    Dreads? That seems to me to be a overly strong reaction. Though if an EV meets your driving needs and you're able to charge it at home, etc. I can certainly see the appeal of not needing to bother with it.
  - lttlrck 11y ago
    Why do you dread going to the gas station?
  - Grishnakh 11y ago
    I don't dread it so much any more. Gas stations have gotten a LOT better in the past 5 years or so, at least here in the South. We've got Sheetz and Wawa, which are actually pretty nice to pull into. Everything's generally new, there's lots and lots of pumps, and if you need to use the bathroom or want to buy some snacks, the bathrooms are usually nice and clean and the food selection is pretty good for a quick-stop place. The newest ones even have made-to-order sandwiches and other lunch food. It's a huge difference from 20 years ago when gas stations were nasty, dingy places with the worst bathrooms in the world. It's not as good in the Northeast, however. Most of the gas stations up there tend to be small and pretty crappy.
