Sorry, but your statement seems to neglect that one should only use chains on roads with snow on them or the chains damage the road surface.
And comparing a decision made by private individuals, to a ‘cost of doing business’ decision made by corporates is not really very realistic.
Why not? An individual’s “cost of doing business” is travel to get to work. If they don’t feel it’s worth spending the investment to ensure that they can get to work every day in all weather, why do we expect corporates to do the same?
How much more are we all collectively willing to pay for this extra level of service/guarantee? Given the way everyone’s flocked to the LCC, then probably not much.
