Even women and the like are required to know how to change a wheel if they turn up for a driving test with a car equipped with a spare wheel.
Fog lights are for fog and snow, nothing else.
Plain water in place of screenwash may freeze, potentially damaging nozzles and/or tubes. You can buy 5 litres of concentrated screenwash in any Applegreen for a fiver that'll produce 35 litres of wash that'll actually wash and won't freeze in our climate. Smells more like vodka than berries when sprayed at the winda. However, a can of dettol air freshener is far more effective for eliminating odours, IMO.
Problems with wheels sticking are generally down to wheel being overtightened which seems to be a trait of all tyre garages. Buy a torque wrench from Lidl and correct the bolt torques after any tyre change / puncture repair and you won't need to carry your breaker bar with you. A light kick of your heel at the top and/or bottom of a wheel that's seized to the hub will free it... Probably best done with a couple of bolts fitted and loosened by 180⁰ just in case it comes off the jack for a belt and braces approach.
