Austin rarely gets icey roads...so when they do, they aren't prepared. If there is ice, stay put and wait for the city to put sand out. It may take a LONG time, but it's not worth the risk of going out prior to that.
avoid driving near the Capitol or Governor Bush's mansion, the police are very strict and will pull you over for anything suspicious. Stay out of Austin on the east side of Interstate 35 - mostly poorer, working class neighborhoods. Don't flash money around in this part of town. Overall, this town is very safe compared to other big cities. Just use common sense!
