I have bought a dash cam for the little car, the main reason being to have some good evidence if we have the misfortune to have a prang with a Spanish car. The driving is not quite as bad as the Aussie standard however if you do have a prang, being a foreigner, it's always going to be your fault!
A friend of ours had a prang with a Spanish driver a few months ago. The Spanish driver lost control and crossed to the wrong side of the road and crashed into their car. She admitted liability in writing but they are still having problems trying to get the Spanish insurance to cough up.
Hopefully with a camera it will make it more cut and dried should it happen to us.
We will also put the camera in the motorhome when we are using that.
I shot a little test clip which shows the road from the villa down to the beach. You can see why we needed the little car, it's a bit tight on some of the bends, plus it doesn't really show you how steep the road is ...
