This is true, but we have a boring vehicle as well and I don't get on the phone while I'm driving that one either.
My TJ is my daily driver, and I usually run doorless and windowless but with the top up because we get a fair amount of rain. I think that configuration is even louder than topless and doorless.
It's been illegal to use handheld cell phones here in Quebec for a few years, but everyone except me seems to do it anyways because it doesn't get enforced unless you're involved in an accident.
