Sorry Roy, I don't think that we will be seeing anything anytime soon...

Mobile TV

Mobile reception of digital stations using ATSC has (until now) been difficult to impossible, especially when moving at vehicular speeds. To overcome this, there are several proposed systems that report improved mobile reception: Samsung/Rohde & Schwarz's A-VSB, Harris/LG's MPH, and a recent proposal from Thomson/Micronas; all of these systems are expected to be submitted as candidates for a new ATSC standard, ATSC-M/H. This is in addition to other proprietary standards like MediaFLO, and worldwide open standards such as DVB-H and T-DMB. Like DVB-H and ISDB 1seg, the proposed ATSC mobile standards are backward-compatible with existing tuners, despite being added to the standard well after the original standard was in wide use.

Mobile reception of some stations will still be more difficult, because 18 UHF channels in the U.S. have been removed from TV service, forcing some broadcasters to stay on VHF. This band requires larger antennas for reception, and is more prone to electromagnetic interference from engines and rapidly-changing multipath conditions.
