Two things i noticed in the film clip, to which i had paid little attention before.

One) the number of cool old cars from the fifties on the streets of 'Frisco.

And
Two) the ability of a single green Volkwagon Beetle that , despite being underpowered and softly suspended, to get in front of the chase at least four times.

I had no idea they were that nimble and fast.
FP has a Blue one and we all thought it was just "cute"
