The question on my mind is?
What effect does using the heating (maybe even heated seats as well, as some people do need them) heated door mirrors and a heated windscreen as they will keep misting up and it’s at night so you need the lights on (maybe even full beam which on my newest car is auto) and it could be foggy so you need the fog lights on also for a bit (front and rears) or the wipers going if it’s wet or spray from the gritting thats been done.. While using adaptive cruise control so the radar & cameras need power also and you travelling at 70 mph for at least, 130 miles of the 140 miles journey.
Plus also your kids need power for their devices (or they’ll have a break down) on the way to grannys which is 140 miles away and of course your using the infotainment system for sounds and sat nav as well.
What then? Is a pretty standard journey we do..
Or the other one i do every other friday to pickup my other daughter from school from the midlands to yorkshire and back thats around another 140 mile round trip.
