Being a vehicle weighing ~3 tonnes & a top speed of 111Mph... I expect all critical systems to go thorough testing. They're the systems which allow safe operation of the truck.
Having bugs in the infotainment is one thing. Having bugs in crtical systems is extremely alarming.
Honestly, from a safety prospective they're doing fine. A fail safe scenario is a safe scenario. From a usability perspective... Well a failure is a failure.
Do you think road safety standards are stringent just for fun? This is a category of products that can easily get people killed with flaws, you numpty.
Stop excusing people selling you garbage, you trash person. I have to assume your standards are trash if you will happily pay for trash.
