This going to take more than "a TNC with you in your car". It will 
amount to a full-blown
mobile laptop  APRS installation.    This assumes the user:

     a)  has a TNC.

     b) knows how to interface it to the radio; i.e. the usual where do 
I buy a TNC-to-radio cable
         since so many users seem to be unable to figure out pinouts of 
devices such as radio mic
         jacks or aux connectors.  And seem to be unable to solder 

     c) knows how to properly adjust TX deviation, TXD, etc.

     d) has a laptop PC to use as a terminal for the TNC to type said 
messages over the air. 

If you are going to go through all this hassle, you might as well just 
run a full APRS application with
APRS messaging in the first place.  

A far simpler "lite" installation would consist of running UI-Instant 
Messenger on a WiFi-equipped laptop.    This application is a plug-in 
for UI-View.   It can also run stand-alone  either directly into any 
IP/Internet connection, or directly into a radio via soundcard interface 
and AGWpe.

The program produces a user interface similar to AOL Instant Messenger, 
Yahoo IM, MSN Messenger, etc. with separate windows for sent and 
received messages, and will handle all the issues of formatting text 
into proper APRS format with the appropriate headers, addresses, etc. 

Of course, it DOES require Windows (or a reasonable facsimile) to
