Amazing that people still think SCs are solely for distance. Tesla committed to DENSITY as well as to DISTANCE 2 years ago, yet threads like this keep popping up along with the exclusionary "if you don't have a garage don't buy a Tesla" and "those darned locals" silliness.
In areas of density, Tesla has shown their commitment - when I bought in late 2014 there was 1 SC in LA County. 6 weeks later there were 3 and they keep coming.
If you travel through an area of density, be prepared to share chargers with local commuters and livery.
The real problem is not the rare local who's clueless enough to use an SC instead of their garage. Remember that the non-garaged are welcome to use SCs unless and until they can get charging at home or work. Municipalities are already starting to incentivize this finally. Just a matter of time.
Meanwhile, here's something we can all work on - eliminating ICEing by our own. Nothing will turn an 8-stall SC into a 2-stall SC than an owner of any kind being late to exit the stall.
And that, folks, is the #1 problem I see in SoCal. Not "locals" who might charge 2-3x/week at most. Not even livery since they're in and out because time is money. It's the clueless owner who meanders off to have a 90-minute dinner during a 40-minute charge. It makes a difference.
As for traditional ICEing, no parking signs, municipal fines and a tow contract solves that and I see more of that correct signage all over the country this year than last.
Vacate the stall when done, folks, or all the elitist handwringing persecution of locals and the non-garaged won't help you.
Also, smart non-garaged locals don't use SCs during peak times. Gonna have to blame the tourists for that congestion.
