Exactly. And look at all the landscaped carparks, with raised pedestrian footpaths, plantings, kerbs, and so on---in Canada, carparks are vast kerbless expanses of asphalt. It doesn't look so nice, but in the winter, the big sweepers can just whip across them and get them cleared in jig-time. There's no simple solution to the problems with snow here---it's very much a mindset thing. in Canada, snow is assumed as part of the equation in everything we do and design, from trains to clothing, because we have to deal with extreme snow for months and months every year. Not so here.
