Well the thing about cards is they can be insured against loss, you can't insure cash. The sooner we move to a cashless society the better.
A card fits easily into a pocket and weighs a lot less than a pocket full of change.
Many modern cars come with electronic driver aids, traction control etc... Isn't that a form of electronic nannying?
And no driver is perfect, every driver makes a mistake now and then. True some more than others and when I had a field based job and was driving tens of thousands of miles a year I saw plenty.
