make a petition at this link for honda to fix the issue you have with the chime. Tell them you want a work around or whatever you're seeking. Then post a link for others to put their name on the list and send it to honda.

the other mods have spoken about the potential issues with future owners of the car. It does in fact pose a specific risk with the way airbags are deployed. Get a petition going for honda to fix the issue and don't make a claim like "I don't like to wear my seat belt... and don't want to listen to the chime". If they were made aware that a large # of people were cutting wires to the seat belt harness to disable the chime, they may see that as reason enough to address the issue. I doubt they want future owners to potentially die because of a chime noise that was meant to be a reminder.... was disabled by cutting it.
