KIT students can travel for free with the KIT Card (only together with the "KVV-Bescheinigung") between 6pm and 6am on the KVV network. To use the KVV network outside of these hours, you can purchase a KVV student ticket. It costs € 150 per semester and can be acquired at the Info Center at the cafeteria lobby and at every KVV-office.
If you want to buy a car in Germany, you should take into account the additional costs (insurance, taxes, fuel price). A convenient alternative is Stadtmobil (only in German), a car-sharing solution.
If you want to drive in Germany with a driver's license from another country, it must be rewritten after 6 months at the "Bürgerbüro" where you live.
