Driving in Palermo and Catania

Hi everyone,

I am a new driver and I drive confidently in Germany but in the city and outside the city. We are planning a summer vacation in July for Palermo and Catania and I can not be sure if I can drive there. I generally have some parking issues but I am okay in Germany because rule is rule here. Do you recommend me to drive car in those cities or do I get really stressed with the chaos?
