Seems to me this is a combination of a set of nannying EU-specific laws (I normally like all this EU biz btw) directly conflicting with allowing the autopilot system to function as it should - IE restricting steering wheel movement, essentially handcuffing the system from manoeuvring cordially - so it abandons movements when it realises it can't complete promptly, or runs wide on corners and applies braking to tighten a radius rather than more lock on the wheel.
This is obviously disappointing and ridiculous for a big list of reasons. Hopefully Tesla can continue to dodge and jump through the necessary hoops to stay one step ahead of foggy, behind the times, stifling legislation with a subsequent update.
