An astute observation on the driver's side cup holder. Not sure what you are referencing regarding the passenger side. I believe they will function well, they are out of the way and most importantly to me, I didn't have to damage any trim. They are also easily removed and installed. I had thought about making something to drop into the bin that would hold two cupholders, but felt it would be a little cramped (not a lot of elbow room now). Just thought I'd share.
