The tracks look good, better in fact with fewer packets than my fixed-interval Kenwood D7 running as KJ4ERJ-8 in the same vehicle.
Of course, your coverage is based on how well tuned your OT2m is, the radio and antenna you have on it, whether it is decoding and listening before transmitting (yes, if you're not decoding, you'll be transmitting over top of other packets resulting in yours not being heard), and the local APRS infrastructure. When all the parts are playing well together, the results are worth writing home about! > Have to experiment more.

If you want to mobile digipeat, it is recommended that you set up for TEMPn-N, not WIDE anything. That way APRS source stations can change their path to take advantage of any pre-configured TEMPn-N digis nearby while those digis silently wait for the opportunity rather than clogging the channel routinely. I think of the Digi/IGate network of APRS as a fabric. Once the local operators get it functioning well, it can really get twisted up in knots if a mobile digi comes driving through doubling up the local traffic with (most likely unnecessary) digis of packets.
