oh, mostly coz (1) he is accident prone - v. absent-minded (2) lots of accidents on bikes here and (3) well, if he is (1), would the bike have a resale value once we leave here.
essentially, a bike is something that we can't bring with us. so we have to sell. much like we have a crappy car here..
but of course i wouldn't point (1) out to his face...
you are Tooo funny parkee! You make me laugh! there is awful traffic here and people drive horribly so I worry about dh every day when he rides a bike...but it makes him happy and he is a good driver so I guess that is the risk... I totally understand that you are in a different position so it makes sense about your doubts!
