Although there are quite a few Lotus owners (and a dealership) in central Texas, there's not really an organized community at this time. For autocrossing, check out Texas Spokes Sports Car Club (spokes.org). Local tracks include COTA, Driveway Austin, and Harris Hill Road in nearby San Marcos. The Cars and Coffee franchise has recently relocated to a COTA parking lot, but I have not been to their new venue. I think it still draws hundreds, so you need to arrive earlier than the posted start times. Lots of nice driving roads in the hill country to the West of Austin. Check out the "Three Sisters" roads for some nice drives.
