I wonder how many calls to roadside assistance (AA, RAC, Green Flag etc.) are from people who have a puncture and either don't have the tools or knowledge or simply don't want to get their hands dirty! These are taking up time and it means people with 'real' breakdowns have to wait longer.
I know people who can't even be bothered to check their oil, radiator or even screen-wash bottle between services - I drove one of their cars once and nothing but dust came out of the windscreen washer jets !! They probably never look at tyre pressures either.
if you are worried about not being able to get nuts off, there are plenty of 'telescopic' wrenches on the market, extend them to give extra oomph when undoing and collapse them to put nuts back on.
