I get that Honda said it's not intuitive to put the Lane Watch feature on the driver's side...looking towards the center of the car when turning left. BUT, I think it should be on the driver side as well. A quick glance to the screen would be helpful.
That said, is the wide angle inset in the driver's mirror any good? It seems pretty small to be of much help.
If you find it to be small, just stop at the local auto parts store and you should be able to find a set you can stick on to both mirrors. Some of them even adjust to different angles for better fine tuning of seeing your blind spot.
