This is a typical example of doublethink.

Sounds like double-talk to me.

Go here to learn about sonic booms, which take place at 1220 Kph. Or
750 Mph.
Wheeled vehicles have reportedly reached speeds in excess of 600 mph.
However friction and resistance of tires, etc. make it hard for a
wheeled vehicle to go past the sound barrier. Airplanes however do it
all the time.

world land speed record - 763 mph

the double sonic booms are audible on the tv coverage.

supersonic!

The offical announcement:

The World Motor Sport Council homologated the new world land speed
records set by the team ThrustSSC of Richard Noble, driver Andy Green,

This is the first time in history that a land vehicle has exceeded the
speed of sound. The new records are as follows:
