I came across something that struck me as rather odd. It is not a big thing and many people will possibly think I am a nerd. I used the BR 155 on the Hamburg-Lübeck route in the rain. I started the wipers with the same speed (e.g. 50%) and they started moving. Of course, they were unsynchronized at first. After a few minutes drive, the wipers worked in perfect synchronicity. Is this a feature? Has some weird resonance effect or other physical oddity been implemented in the game? I am still very flashed by this experience. )
That's normal, they are still controlled independently and the wipers have sometimes 'lag', like real life.
It's the same thing with the DR BR243 DB BR143 both windscreen wipers are controlled by switches on the left and right sides of the Driver's cab. One is valve second is turn on. What version of TSW 2 are you using Gen 8 PS4 or Gen 9 PS5 64 GB DLC max?
I'm on PS4. When I turn on the wipers on the 143, they are also asynchronous, but they stay like this. On the 155, after a few minutes, they have exactly the same rhythm.
