The idea is simple , if motor_vehicle=* is used and motorcar is not set,then
set motorcar=* to the same value. Note that the action is add, not set.

The line 46 is preceeded by this:
# throughroute cannot be handled differently for different vehicle types  

It means that the Garmin format has only one bit that means "allow no
through route"
So, if we find motorcar=destination we set the flag. 
If I got that right, the flag is ignored when you select a bicycle as
vehicle when routing with
Garmin software, so the solution seems to be ok for me. One who creates a
map for trucks
should change this rule.
