The problem is that all motion is relative. All of us are constantly travelling at anything up to about 1600km/h (depending on our latitude) as the Earth rotates. And we’re also doing 173,000km/h as we orbit the Sun and 720,000km/h as we orbit the centre of the galaxy. But we aren’t ever really aware of this motion, so maybe it doesn’t count as direct experience.
The Space Shuttle has an orbital velocity of around 30,000km/h, but the crew of Apollo 10 hold the official record for the fasted manned vehicle when they reached 39,897km/h relative to the Earth on 26 May 1969 during their return from lunar orbit.
