I doubt it. The 2022 M3 RWD had brought the below 2 major benefits to the owners (according to many FB & forum posts):
So the 0.5 sec performance reduction had moved the M3 RWD just out of the "performance car" category (0-100 under 6 secs), used by both insurance companies & Service NSW to calculate car accident risks. Any performance boost option offered by Tesla will simply remove the above benefits, as insurance companies & NSW police wouldn't be able to reliably detect whether an M3 RWD has the boost option turned on.
- Cheaper insurance premium
- Can be driven by P-platers (at least in NSW)
I don't think Tesla made the car slower to make it Australian P plate legal... How many P plate sales do you think they will have? Our entire EV market is small fry let alone just the P platers. May have similar reasons in Europe though.
They could easily offer the boost and put a disclaimer on your account that you must accept. 'This will prevent the car from being P Plate legal in certain states and territories and by accepting you confirm no Plate drivers and may be necessary to notify insurance providers' it would be that simple.
I don't think the police would care. It's not like a p plater can't borrow another car that's not legal for them to drive and drive it anyway. Or mod a car and keep those mods hidden.
