I travel on 4 wheels with bike based friends and love my SPH10 and being able to chat en route. Would like to be able to do the same with my car club friends, but with a single intercom base or something along those lines, with multiple passengers in the vehicle. We used to make do with walkie talkies for emergencies, but they're rubbish, and I can't even bring myself to carry one after using a Sena and knowing what is possible. Missing out on a big market.
How about an automotive based application
