My point was not which highway was getting the most traffic. It was questioning which highway Tesla owners were likely to use. If you already live in Austin, you're starting out for SA with a full "tank" anyway, and you wouldn't use the San Marcos SC. Where that station will come in handy is for Tesla owners going to and from SA from DFW. Most of them would be bypassing Austin anyway. Personally, I would rather travel on a fast road with very little traffic rather than having to deal with Austin traffic if I'm just passing through.
The 130 toll road is still an option for people coming down to SA from Dallas. You get on 130 at Georgetown, bypass Austin, and then take the 45 Southeast tollway back to I-35 just north of the supercharger in San Marcos. That's a more direct route to San Antonio anyway.
As for us Austin owners, I have a 60 so the San Marcos supercharger will be very handy for me getting back and forth to San Antonio. Otherwise I have to charge quite a bit to get enough juice for the return trip...
