Travel mode is interrupted when reaching 20 km/s

[Hupf]

Using the Yasur and some level 3 hull and drive mods, I was able to get a maximum travel speed - on paper - of 36 km/s for a ship.
When I pilot it myself, I noticed that shortly after engaging travel mode, it is interrupted automatically. At first it seemed like some sort of collision prevention (asteroid field), however after further testing I noticed that it happens repeatedly just after reaching 20 km/s, so that seems more like some hard coded safety feature to me.
Needless to say, I'm practicing safe flying by always buckling up and not consuming any Spaceweed!
