I work in Barcelona and live in a town 20Km outside it. I drove back home just fine at around 16PM. Some traffic in the city, but manegable. My town has had electricity in homes since 15PM, some neighbourghs told me. At night I drove to my parent's (different town, 10km away) since I couldn't communicate with them and was worried. Their town was pitch black. People were driving mostly safe and slowly. Of course you get the random POS that doesn't care, but I didn't feel in danger at any moment. My parents were fine. I drove back home later and same story. I just woke up (it's 7AM here) and the Internet is back and I have a message from my parents, their electricity is back too. Overall, I didn't see any crazy behaviour.
