Hi Michele,
there is no such function and I don't think there will be one soon. One
workaround could be to retrieve the vehicle ids on the current lane
which are sorted by position, look for your vehicle and take the next
one. This is not documented but unlikely to change. You could do a
double check by asking the resulting vehicle for its leader. But this
will not work across junctions and I am not sure what it returns in the
sublane model.

Best regards,
Michael
