I'm not sure vehicles on rubber tires are particularly well grounded.

Normal tires have carbon added to the rubber to make them slightly conductive, enough to drain static.

Specialty tires like you find on drag cars do not. This is why you also see grounding straps dangling from drag cars -- to keep the driver from getting a shock when they step out after a run.

"grounding" in this case refers to equalising the potential difference.
