OK, I'm gonna modify my last response- Austin *is* generally OK for low or zero car. I've been here three years now, and I'm bike commuting from Cedar Park to The Arboretum. Eleven miles each way. It's hot but not dangerous. I'm fortunate to have showers at each end; I get pretty wet even in the mornings and I'd be pretty stinky without. I pass three HEB's (grocery stores on steroids) and two bike shops on the way, and I have bike lanes, wide shoulders and back roads the whole way. It would be very easy to get rid of the car... but I'm not quite there yet...
