Maybe with the car, you could see it flying by (in the distance, where you can’t get to it, presumably filled with survivors) as zombies are trying to chase it and jump on top of it. As a sort of foreshadowing. Something to that effect.
Or, maybe it could be barreling towards you (on the other side of a fence/gate/large glass wall like in a plaza) with zombies all riding on it, trying to get inside, and it eventually flips. Taking out an obstacle and allowing you to continue… (I always picture a van, like the on in the airport in dead air)
Finally, perhaps you could be walking through an area, and just as you think you’ve hit a dead end, you hear tires squealing, and an engine revving up. Then… BAM!! It just un-expectedly rams its way through what appered to be a solid wall.
EDIT: Collapsing bridge? Maybe you think you’re supposed to continue across a bridge toward wherever it is you’re headed, but then the bridge collapses, and forces you to take a trip through some L.A. style canals. (Or the sewer, but that’s kinda played out). Or down a large freeway. As if the bridge were an overpass. Or if the bridge was part of a highway you’re already waling on, and it dumps you out into an underpass, onto street level. Mix ‘n’ Match whatever you like… ;c )
