A friend of mine advised me to think about renting a car in Portugal in advance, and I'm glad I listened to him. Using the
https://roscar.pt/car-rental-madeira/ website, I was able to quickly find and book a car without spending hours comparing different services. I picked up the car in Porto, drove along the coast, and then returned it in Lisbon. The conditions were clear, nothing was imposed on me, which was especially nice.
