> In subzero conditions you shouldn't use your car's handbrake when parked - leave it in gear, with chocks under the wheels in necessary. Perhaps there should be a BMG car parking module.
It's a digression from the great article but do you really think that people living Canada, sweden, Norway etc.. don't use their handbrake for several months of the year?
Service your brakes regularly, clear the crud etc and if parked up for many weeks 'then' consider not using the handbrake.
