- You are more flexible about which side of the road to drive on. I have noticed I tend to switch which eye I look out of when I look in the rear view mirror and I switch between using the interior and exterior mirror. If your home country drives on the right and you are right handed, while using your left hand will feel weird, you will have an advantage over others because you are on your dominant side either way. (For instance, in the US, I am on my dominant hand side, and in the UK, I would be on my dominant eye side.)
- You might become better with your non-dominant hand or used to using your non-dominant eye. My right eye has much weaker vision than my left eye (I wear eyeglasses), so as I said, I had to choose whether to use my better hand and worse eye or my worse hand and better eye to do archery (and I chose the former, as I usually do). However, you might decide to try using your non-dominant hand more often and you might become better at using that hand than you would be if you were not cross-dominant.
Sorry to be blunt but I will finish this later
