The first video/tune is utter cr*p. The video on the last one is worth watching for the bike tricks. The track is ok but is being done by so many these days. Take it away from the studio and what have you got? Definitely not something that could be reproduced with any quality in a live situation.
Drove my Zed daily every winter for the last 7 years without a problem. The old adage "drive to the conditions", whatever they be, has always been my way. Smooth & gentle and you shouldn't go wrong, but always allow room for the idiots.
