Maybe i should be more elaborate. Being tired in long hours
driving is unavoidable, i understand that( even the truck driving
simulator , 18 Wheels of Steel: Convoy, which i played for 2 hrs
non-stop driving a "truck" i felt very tired oredi, let alone real
driving).
But what the BC did i think was a mistake. Instead of washing his
face to perk him up, he went behind the bus to SLP. Try like this,
u wake up in the morning and its still early, you went back to slp,
then u woke up again 5mins later, surely you will feel like
sleeping again rgt? And u will feel even more tired after the
"nap". Maybe a 2hrs nap will be sufficient, but i think a 5min nap
will make you feel worse, that's what i think. Everytime when i
wake up and its still early and i went back tp slp for another
5-10mins and wake up again, i confirm will slp in class. If i wake
up and its still early BUT i never go back to slp and instead wash
my face, i would stay awake in class. 
That's what my dad told me, "If you wake up, dont go
back to slp, otherwise you will feel even more tired and will slp
again".
