Yeah, I knew of at least one trucker who's on the local linked repeaters in western NY. He used to sell the raffle tickets at our hamfest, haven't heard from him in a while, tho.
I know bands are wide open now, and 10/11m will quiet up when the cycle dips again. All the people (or at least most) that shun Ham radio because of licensing fail to see how it keeps the band from becoming this much of a mess.
I guess GMRS would be the next logical step for having local communications, but I don't see that being adopted for over-the-road type travel. Maybe something in the old 46mhz band that fire and ems used to use might be cool. But, the 6m ham band is mostly dead, just a couple repeaters around here.
The FCC is more interested in revenue than giving people more options for license free operation, tho.
