CDW is just about the car !
Make sure you also check your health insurance and liability policies to make sure that you have coverage for:
1. Medical costs you may incur
2. Liability to third parties (you hit and injure someone)
3. Air evac (in case you want to be treated back in the USA)
The CDW is nice, but it's just about paying off the vehicle if you wreck it. Cost of a broken leg can well exceed that.
