A scooter and raki do not mix. Nor does a car obviously but I mention scooters in particular because most people who rent them don't really have a lot of experience with riding a scooter and a great many of the accidents that tourists have happen when they mix drinking and riding. When you place emphasis on wanting to drink raki, you raise the red flag of the possibility that you will drink and ride which is never a good idea. While I certainly don't advocate drinking and driving a car either, if the possibility exists that you will do so regardless of common sense, then you have a better chance of surviving an accident in a car.

I knew one acquaintance who died from a scooter accident and another who ended up in a wheelchair. Both on the same Greek island (Rodos). The first had not been drinking, the second had been. Scooters are higher risk of serious injury/death in an accident. That's just a fact. So unless you are an experienced rider, you are always safer renting a car.

The same issues apply to ATV rentals by tourists which are quite common on many Greek islands now. The tourist is not experienced in riding an ATV and 'flip' them over.
