inception van fall special effects error

inception van fall

i was watching inception while working.

actually i was listening to it.

and i noticed a really obvious special effects error.

in the scene when van falls of the bridge, the van is super slow motion

but the snowflakes are falling at normal speed.

if van would go back to normal speed and if snowflakes would accelerate equally

the snowflakes would move at the speed of light

and would cut through human skulls.

funny how with all the special effects still silly mistakes are made.
