I live in Boulder. We are probably one of the most uptight, green, Pro-EV, tree-hugginest, crunchy, granola cities around AND the home to Elon's Brother's flagship restaurant - The Kitchen - and the closest SuperCharger is almost 40 miles away.
I think they just don't want people using them for anything but long trips.
That is definitely true and I fully agree with and support Tesla's policy in this regard. But Boulder (and Seattle) are just underserved --- even for travelers.
As an example, I visited Boulder on a long trip earlier this year and had the exact same thoughts and experience. People tell me that Elon is often seen in Boulder, and yet as a visitor I found Boulder to be a very difficult place to find working and conveniently placed public charging stations of any type. No doubt Elon's brother has a HPWC installed at home, but if you are a visitor who is not staying at the Boulderado or Best Western, you'll find your EV charging options (Tesla or J1772 quite limited! I visited the solar powered charger in a public parking lot on Broadway, but it didn't work. Had better luck with the free-for-customers chargepoint at Alfalfas Market but you're limited to an hour at 30 A so that wasn't very practical for Tesla owners. There are other parking garages with J1772s available on the east side of town if you happen to be staying there. As a visitor staying with a friend on the west side who did not have a 220 V outlet installed in his home or garage, I was forced to charge in Denver (art museum or SC) or Fort Collins (day trip and visit) during my stay in Boulder.
But the original post was about Seattle, and I whole-heartedly agree with the sentiment expressed there as well. Had I not stayed at a Capitol Hill area B&B with a destination charger, actually exploring Seattle would have been impossible. My Seattle B&B experience was great, but the dearth of charging options (Tesla or otherwise) in the greater Seattle area made visiting destinations along the Olympic Peninsula quite difficult. I do have sympathy for Tesla in that the Seattle area is not an easy one to equip with all of the interesting geography and waterways...
Seattle and Boulder are two of my favorite destinations and two cities frequently associated with progressive environmentally-friendly residents. But I found neither to be very "Tesla" friendly. Hopefully that will change....
As for Oregon, I personally did not find moving about Oregon as a visitor too difficult at all, even with the lack of coastal Superchargers earlier in the year. Lots of options where I needed it and also lots of destination chargers where I wanted to stay. And it appears Oregon is going to be even more nicely equipped by the end of year.
