Yep,...he's king ! I've got a set of drivers like that big-one,..cheap and
solid.

I wonder how much she would scream if he actually drove fast, he looked
like he wasn't pushing the car all that hard.

Neat trick, but the generator pulley appears to have been modified to
allow it to work.
IIRC Beetles all had a 32mm hex nut that held the pulley halves
together and a slot in the lip at the edge of the pulley to lock it
while the nut is being undone or tightened. The spare shims for
adjusting the belt tension lived under the nut. This one looks to have
a bush attached to the nut, and possibly to the outside pulley section
as well, with no slot in the lip.
Also note the dents in the lip left by screwdriver blade when he's
been practising.
FWIW I've seen much the same trick done with large section belts using
a block of wood. Forcing the belt against the edge of the driven
pulley just before top centre causes the belt to lift up and jump over
the edge. Makes a puff of smoke and leaves a nasty groove in the side
of the belt though.

Watching it again it's somewhat simpler. He only jams the screwdriver
handle against the pulley to stop the generator motoring... it doesn't
loosen the nut holding the pulley halves together. The slot normally
used to lock the pulley is on the inside half closest to the generator
(no modification required there).
He's stretching the belt over the crankshaft pulley by levering it
with the screwdriver. The belt doesn't appear to very tight when he
does the trick (ie it's not correctly adjusted).
Shouldn't be difficult to do with a bit of practise so long as he
doesn't mind the damage to both pulleys and the belt.

And generator bearing.

The other end of the generator, has the cooling fan on it, does it not?
VW bugs are one car I haven't owned. A friend had an automatic Kombi.
Believe it or not, VW put reduction gearboxes on each axle due to lack of
power/torque. Incredible when you consider also, that early Kombis had less
than 40 hp :-)

Very unlikely IMO.
