Whilst waiting for my call to say that my M3LR has arrived and ready to be collected, I am having second thoughts of whether I should have the FSD at £4900. It can do Lane change - useful if there are less BMW/Audi drivers on the motorways Navigate on Autopilot - does it work properly in the UK with so many roundabouts Self parking - cant see myself using after showing off a few times. Advance summon - most likely to use as it would be nice for the car to drive out of the garage or from the sainsbury carpark to pick me up. Robo taxi - yeah..... But is it worth £4900? But if I cancel FSD (can i?) will I be push back to 2020 delivery.
