This is a bad faith argument, but I'll respond: 150km/h is not arbitrary.
In most Europe, highway speed-limits are between 110km/h and 130km/h [0] give or take 40km/h to 20km/h to get out of a dangerous overtake and 150km/h should be more than enough for most cases.
Notice I added (consistently) for clarity, there are very rare cases where one needs to accelerate, but I find it very hard to justify a car going almost twice the highway speed limit for 30 minutes non stop.
