The meter is a super precise definition of an old bar of metal made by French people to guess at an absurdly small fraction (1/10000000) of a distance between two randomly chosen parts of the Earth (but runs through Paris).
Winter driving safety advice: 1. brush ALL the snow off your vehicle (not just a hole to see through). 2. turn your lights on (not for you, but for other people to see you, especially the snowhats who didn't completely brush off their vehicles.)
I like that in Swedish, the saying "practice makes perfect" (รvning ger fรคrdighet) actually translates back to English as "practice gives you skill".
