I kind of already have walked away from this technology some years ago, particularly in these harsh economic times.
I no longer have a car, living in London, as i do its, just too crowded on the roads, most of whom are idiots any way. And the cost of running a car these days with fuel, tax, insurance, maintenance, congestion zone charge, ultra low emission zone charge, renewing driving licence, parking etc. (geesh that list got long very quickly), it's just not worth owning one more... all those wasted hours and cash learning to drive all those years ago haha!!
If I need one for a long journey I'll hire one, but other than that keep them.
