how come wind can push my heavy box-shaped car around when I’m driving 60mph, but it can’t do it when the car is standing still?

Question

Although I have a heavy box-shaped car, I was thinking about the Mercedes G63 specifically. That is a powerful engine on a non-aerodynamic car, what happens if you take it over 100mph and get hit by a gust of 60mph wind? My car gets literally pushed around lanes during heavy winds at highway speeds, has anyone ever even gotten a G63 past 150mph?

Real answer: because of inertia.

ELI5: if you place a marble on a table and nudge it with your fingertip it moves maybe 2-3 inches in that direction, if you roll it down a ramp but also nudge it the same way it will move many, many more inches in the same direction than if it was sitting still.
