Lack of spare wheel is such a
Lack of spare wheel is such a serious issue, all Dealers should be legally required to disclose the spare wheel status.
Armed with that knowledge, I suspect more car buyers would demand a spare - or threaten to go elsewhere.
Maybe not 100%, but enough to make an impact.
Also, car dealers should be banned from repeating bogus stories about "very few punctures".
Most people I know average a puncture every 3 to 5 years.
Not often, some might say.
But everyone I know can change a wheel in 15 minutes ( and they're not all mechanics !).
By contrast people using other methods report either:
a) the gunk filler takes longer to understand and make work
or
b) it fails to work, so they wait hours for help
(perhaps in a remote area, in the dark or in the rain)
c) the minor puncture cannot be repaired.
