In theory, it'd work fine, assuming you're connected long enough to associate (and authenticate, if there's security), and transmit/receive all the data.
Depending on the AP coverage, you might not be connected for long enough. If you're moving only within the coverage area of a single AP/bridge (such as within a warehouse or open area), then there shouldn't be a problem.
It may sound counter-intuitive, but sometimes you want more distance.
If you can put the AP a few hundred feet (D) from the vehicle's path and use an antenna with, say a 90 degree azimuth, then the car will be in the cell for D*SQRT(2) feet, but always at about the same distance from the AP - reducing the problems that a fast approach/departure might cause.
