Yes it's possible. I even considered doing it. It was a very brief debate though. I've been cut off in traffic more times than I can count, and they usually act like they didn't see the car. I don't want to make that worse.
I would at least put a switch on them if I ever did this. That way I could run them if I wanted to, and they wouldn't just be disabled.
There are several threads on here, like those listed above, discussing how to do it if you are determined.
