People will drive into anything. Yellow school buses, Police cars with their beacons flashing, anything.

You're talking about taking the lane at a time when there's snow and ice on the road, and when there's a dazzling sun, and when there are on-coming headlights..

It doesn't matter what you put on the back of your bike, if you ain't gonna be seen, you ain't gonna be seen - don't put yourself in front of such vehicles.
