Kalshane, my two cents says "worth the effort".

Maybe make up a thermos of hot chocolate the night before or some other sort of fun stuff to eat in the car?

Oh, and as the mutated fruit flies wreak havoc, the drivers of the cars in the car chase have to put aside their differences and join up with the scientist and his girlfriend (who is also a scientist and who looks like a 20 year old model, except she wears black plastic glasses) to defeat the mutant fruit flies.

The owner of the fruit stand, who is an offensively stereotyped immigrant, adds the comic touch.

Shouldn't there be a spunky kid somewhere in this scenario? Possibly helping out his wise grandparent at the family fruit stand?

There could also be a monkey. He periodicaly steals fruit.

There also needs to be a dog who gets into peril...but lives, of course!

And maybe there's a place for a Native American, who's in tune with the spirit world?

And from out of the woodwork appears an old grizzled Fruit Fly Bounty Hunter.

On another note, Darwinism? [link] 22 y.o. rapper kills himself accidentally with pen gun.

Maybe the fruit stand owner is a retired organ grinder and the monkey is a retired organ grinder's monkey. Eventually they determine that the frequency of organ grinder music repels the giant fruit flies.

Don't forget the grumpy but good hearted black guy in a position of authority over our protagonists who gives them a good cigar-chomping chewing out, replete with threats of suspending their vendor licenses.
