I haven't looked into the sourcecode. But on my etrex I can choose the 
types Motorbike and Car (beside HGV, Taxi and others), so there has to 
be some difference. As far as I know, these access restrictions are 
handled by different bits.

I personally don't like to have this dependencies hardcoded in the java 
code. I think it is the use of the style files to map different osm tags 
(like the motor_vehicle) to specific garmin ones. So each user can do it 
to his own thoughts and use cases.
