Question about air turbulence?

So would it be safe to say that a large commercial aircraft flying overhead
at a stupidly low altitude like 20 feet wouldn't be nearly strong enough to
overturn vehicles?

How fast does air around the fuselage of a plane move compared to its
velocity. for example, if a plane is flying very close to the ground at
300mph per hour over my head, will I get blasted by 300mph gust?

let me know. thanks.

No -- you might feel some wind as it goes by, due to air
displacement/replacement, but nothing like 300 mph. Remember, the air is
standing still, with the plane flying through it. What you will feel is
the turbulence due to air friction and lift -- sort of like what you
feel when a car speeds by.
