In general, the trucks that pass me on the highway don't wait until I flash my highs (which I'm perfectly ready to do), but cut me off when there is some fraction of a carlength between them and me. Perhaps they aren't expecting a signal from me, since I'm driving a car and most car drivers don't give this signal. Is there any NAK signal other than blowing the horn (which can be interpreted as an unkind gesture)? Tom Laidig AT&T Information Systems Laboratories, Denver ...!ihnp4!druxu!tll
