It’s not a massive issue, just be careful if using paddles to level 3 while on downhill slopes when there is lots of ice/snow on the roads.
Also when in winter, I used to use preheating in the morning but now Octopus rates rates have changed I just get in and press heated seats/heated steering wheel and autohold buttons. I used to drive carefully and try to do most miles to the kw but now just enjoy the comfort! The other thing is the how quickly the heat comes through, much quicker than in ICE cars.
