     The correct setting may be dependent on the car-following model in use. This is especially true for `accel` and `decel` which
     usually do *not* denote the maximum values achievable by the vehicle but rather the convenient values. If you use a different model than Krauss you should probably revisit the values.
 
+Please note that `personCapacity` and `mass` do usually not include a driver in the tables below.
+(So a bicycle has a capacity of 1 and this does not mean the children's seat but the driver; and a mass of 10kg
+obviously does not include the driver.) The only exception here is the default passenger car which has
+a capacity of 4 while the average car out there has probably rather 5 places. But using all 5 places is
+probably rather exceptional so the historic default has been kept and it is maybe the better value for taxi scenarios as well.
+Please also note that the mass in the handbook
+of a private car usually *includes* the average driver's weight.
+
+Whether the exclusion is correct or not also depends on the way you set up the simulation. If persons are
+modelled explicitly it is right, if not, you probably do not care about personCapacity and variable mass anyway,
+but if you do please revisit your vType settings.
