With all the hype about supercharging stations being installed nation wide for the Model S, there are no plans to include a charging outlet( HP 70A or Nema 14-50A ) for the Tesla Roadster owners at the supercharging stations.
In Texas I understand there will be supercharging stations installed between Austin,Dallas and Houston for the Model S.
I presently will have to rely on the Level 2 or Level 1 stations installed by Blinks,Chargepoint and others, which will make any travel experience unpredictable.
Elon and Tesla should continue to support the Roadster owners who supported Tesla from the beginning.
At the present all the attention is on the Model S.
In the beginnig Tesla installed chargers along the west coast for Roasters with the promise of more to come, that has now taken a back seat to the Model S rollout
The cost to include charging outlets for Roadsters at the supercharging stations nationwide would be a minimal amount to Tesla but a huge statement as to Tesla's intention to support its customer base and the charging needs of all the Tesla owner family members.
