Currently average distance between chargers in USA is 80 mile.
Average distance between gas station in USA is 6 mile.
If Tesla can get to 10 mile average distance between chargers, and increase charge rate to 200-300KwH, it's the end of "Range Anxiety"
In order to get to that point, Tesla needs to have 64x current charger station count. I think that instead of creating all 64x more charger station, Tesla could build 8x more charger station, but also multiply the number of stall by 8x. That way 8 x 175 current station count = 1400 station. Most station currently have between 4-6 stalls. Tesla needs to reach 16-20 stalls in each station (just like most big gas station)
End of 2014 = ~150 superchargers in USA, 300 Worldwide
End of 2015 = aim for 300 superchargers in USA, 700 Worldwide
End of 2016 = aim for 600 superchargers in USA, 1200 Worldwide
End of 2017 (gen 3) = aim for 1200-1400 superchargers in USA, 2500 Worldwide
2018 = double # of charging stall, install solar powered and stationary storage in 25% of superchargers
2019 = double # of charging stall again, 50% of stations solar and battery powered
2020 = double # of charging stall again, 75% of stations solar and battery powered
There is no more Range Anxiety. People who live in an apartment will also be served. That will be the electric revolution that we need.
Couple all that with ChaDeMo charger. Plus the appearance of Solar Canopy + electric charging in parking lot. That will be the ideal infrastructure for the electric revolution. No more excuse to not go electric.
The math is also very simple for gasoline savings too. Buy Model 3 for $35K to $40K. use it for 10 years, save $20-25K on gas, truly just buying $15K car. That's the entering the area of no competition. Not to mention if they introduce Gen 4. for $25-30K, with fuel savings $20-25K, it's essentially free car over 10 years.
Sell net-zero energy home package. Solar Panel + Stationary storage + Model 3 car for as low as $600/month for 72 months + extra charge for excessive usage.
This may read too over the top, but anyone who ever played Sim City knows that this is the future of energy. No more fossil fuel, all clean energy.
